Luciani's conclusion: between 1pm and 3pm PST (after lunch) or between 5pm and 7pm PST (after work) are the best times and Thursday is the best day. The worst time to post? Between 3 and 5 PM PST on the weekends - nobody cares. See the graphs below.

In the graphs below the factor measured is what AideRSS calls a PostRank of 6 or higher. AideRSS looks at all the items in an RSS feed and scores them (relative only to other items in the same feed) in terms of number of comments, number of Diggs, number of times saved to Del.icio.us and number of inbound links from blogs. The highest percentile of posts in a feed have PostRanks closest to 10.

These graphs then measure which times and days see the largest numbers of posts submitted that end up being more popular than other posts in the same feed. So the most wildly popular and discussed items among all popular items at Digg, etc. It's tracking the time that the post is submitted to the news site - not when it was necessarily posted on the blog. It's a touch obtuse and it would be nice to read a little more about the methodology employed - but the PostRank algorithm is relatively transparent and the conclusions are intuitive.

This is just one of many things we've written about using AideRSS for here at RWW. It's a simple and very powerful tool that I at least use every single day.

Note that of course people blog for more reasons than just popularity and popularity cannot be equated with popularity! If you're in a hurry it is one way to look for quality, though. :)

With no further ado, knock yourself out wrapping your mind around these graphs. I almost did; remember that times here are GMT and if you're on the West Coast of the US, I hope you just had a nice lunch and remember to subtract 7 hours from this 24 hour clock to figure out these times for yourself.

Thanks for the creative and valuable work, Jake!

Whether or not you're an avid StumbleUpon user, whenever news is slow and you're dying of web boredom, StumbleUpon is a great site to visit!

One way to optimize what you stumble upon is to add people who are active users of StumbleUpon, and who are stumbling your topics of interest. To do so, you can use StumbleUpon's search tool. Type in any keyword, or even a brand, and you'll get plenty of results to featured sites tagged with your keyword.

StumbleUpon Search

Afterwards grab the StumbleUpon toolbar, which is available for both Firefox and Internet Explorer. Once you have the toolbar installed, simply select the 'friends' channel in the 'Channel' area on the toolbar and click the 'Stumble' button to browse through your friends stumbles. From there, you're guaranteed to find at least three new articles or web services.

Twitter

For some, Twitter may be just a bunch of noise. If that's the case, you're not following the right people. Some of the most avid web surfers are also using Twitter and it's not uncommon for great content to be passed along or 'retweeted'. Keep an eye on your followers for links, especially when news is slow. Someone is bound to tweet something interesting and newsworthy before the day is over.

Friendfeed

Early adopters of web services share some of the best content out there. This is content that may be a little harder for the average user to find. Friendfeed is a prominent new social aggregation service that quite a few early adopters are using - not only for aggregation purposes, but also for sharing great content that they find.

By using the highly recommend Greasemonkey script that allows you to filter Friendfeed by service, you can cycle through what's being streamed from blogs and Google Reader Shared items to find some great content.

LinkRiver

LinkRiver can be your personal Techmeme, because of the many articles that are being shared on it by the users of the service. Here, you can find some of the hottest articles being shared today or this week by 90% of the LinkRiver community. The "LinkRiver Popular" section is a great place to start your search for more content. There are more than a few gems in this section that can get you through a slow news day.

Techsted

Techsted is a relatively new memetracker. However, it's doing a great job of not only finding great content from the biggest networks out there, but also from various "B-list" sites and bloggers. A great thing about Techsted is that it's not limiting itself to strictly tech content. You can also find content about the latest topics such as deals, launches, announcements, how-to's, questions, SEO, web design, and more. All of this can be conveniently found on the Techsted Dashboard, a new section of Techsted that's reminiscent of the Alltop website.

Social Bookmarking Sites (Del.ico.us, Diigo)

Last, but certainly not least, social bookmarking sites can be a great source for finding content on a slow news day. Sites like Diigo and Del.icio.us feature everything from recently bookmarked sites to the hottest bookmarks at the moment, all conveniently located on their homepage. No need to add any friends or even sign up, although doing so can help your hunt for more content tremendously.

If you happen to have friends on these sites, pay attention to what they're bookmarking. Just like with StumbleUpon and Twitter, if you're following people sharing similar interests then go through their bookmarks. You'll never know what you'll find until you do. After all, isn't that the point of these services?

Optimization Tips

These 6 services are great additions to any network and valuable resources for everyone. For better optimization for most of these sites, remember to:

• take advantage of the search feature
• use keywords or tags when searching
• add friends or people with similar interests (if possible)
• check the site's homepage regularly

With these four rules to optimize your search results, you're guaranteed to get through those slow news day blues!

The highlight of the new version is recommendations. The new Diigo offers a number of social networking type features that in-and-of themselves aren't worth a lot to me, but if they can do some number crunching and recommend people and content that I may want to subscribe to - that's gold.

What's the biggest crime committed by Del.icio.us? It's not leveraging the huge amount of data the service holds for some recommendations. Why on earth, in this data-centric era, isn't every social bookmarking service making bookmarking social and smart? If Yahoo! held an Amazon-style contest for recommendation algorithms that could be run against Del.icio.us, they could set up a Yahoo! News style page that was personalized like nobody's business. We'd all come back daily to read Del.icio.us, they could run ads up the wazoo and everyone would be beside themselves with happiness.

Instead we'll have to look to a pre-acquisition startup with neither network effect nor scaling problems. Diigo has potential to change the social bookmarking game just because they are offering recommendations. The recommendations aren't even very good yet because there's very few people using the service and the algorithm appears quite simple. I imported several hundred bookmarks from Ma.gnolia and perhaps Diigo will think deeper thoughts about my history after a few hours. I'm not so sure, though. It's still worth a look because it has so much potential.

You might also like the annotation features, though in all likelihood they will prove more trouble than they are worth unless you're an academic. You can associate an OpenID account with your Diigo account now, too. That's good.

Trust

Checking out Diigo could be pretty pain-free. The service does a good job of importing your bookmarks from elsewhere and allows you to publish simultaneously to your account at Del.ico.us, Ma.gnolia or Simpy. If, that is, you are willing to trust the Diigo people with the password to your usual social bookmarking account. Doesn't Ma.gnolia at least have oAuth support so I don't have to do that? Discussion about user authentication protocols as part of data portability seem common enough by now that it's outright offensive to be asked for your password to another web app. If you can deal with that, then there's no reason not to give Diigo a try.

Check out Diigo for yourself, it could be just what you're looking for. It's getting closer to something I can imagine using regularly and really appreciating - but it's not there yet. I'll keep an eye on the recommendations feature because if that ends up working out well, it would be reason enough to switch to Diigo.
