Blogging and stuff sharing service Posterous.com now publishes real-time PubSubHubbbub feeds for every site in its domain, the company announced yesterday in a blog post about a number of major revisions to the site. That means that real-time savvy content aggregators will receive Posterous content almost instantly after its published, instead of waiting as much as half an hour to poll the site for updates.

The company is using the service Superfeedr to outsource its Hub management. Posterous joins WordPress, Blogger and TypePad among the popular publishing platforms to offer real-time feeds.

Last week we took a poll asking for your favorite 'light' blogging service. These are blogging services that make it very easy for you to share content and media. While old-school blogging service Blogger.com got the most votes in our poll, newer slicker services such as Tumblr, Soup.io and the recently trendy Posterous are popular with early adopters.

Many people are only just coming to know the newer services like Posterous, so in this post we give you 5 tips to get the most out of them. The post is in the same vein as our earlier How to use Facebook one.

Earlier today we reported that Posterous, a popular minimalist blogging service, had added the ability for its users to import their Tumblr content. Tumblr is a competing 'light blogging' service - the market leader in fact. Other similar services include Soup.io, Noovo, Vox, Profilactic and even Wordpress.com and Blogger.com are used for this purpose (although they're more used for long-form blogging).

We're curious to know which of these services our readers use. Let us know in the poll below, or make a comment if yours is not listed.

Posterous, the popular minimalist blogging service, just released a major update to its service, which includes customizable themes, a feature a lot of users had been waiting for. Users can now choose between five different themes, all of which are highly customizable. According to the company, additional themes will be added over time. Users can now also easily import their Tumblr blogs and even use their Tumblr themes as Posterous now also supports the Tumblr theme format. Posterous also announced that its traffic grew tenfold over the last 12 months to 4.4 million unique visits last month.

Posterous, the increasingly popular minimalist blogging service, just launched its first iPhone application this morning. The app, called PicPosterous, allows users to upload pictures and videos to their blogs. Until now, the only way to upload this content was to email it to Posterous. The developers of the iPhone app still have to work out some kinks, but once the company fixes these issues, PicPosterous could quickly take over email as the most convenient way to upload media files to Posterous.

Posterous co-founder Gary Tan just announced that they've acquired fellow Y-Combinator company Slinkset - a Digg / Reddit-style news site with voting capabilities. Says Tan in his blog post, "Slinkset will remain online, and we'll be working on some crazy awesome stuff to bring the power of Slinkset's technology and community to your Posterous experience."

The Posterous experience has certainly improved since its initial launch in 2008. In the past few months alone, the company has rolled out a variety of new releases including a faster blog importing tool, group blogging and the ability to add comments from Twitter and Facebook accounts.

You may not believe this, but there are actually people on Twitter who don't have blogs, use bookmarking services, or contribute to review sites. Don't judge. Maybe they're busy, or bucking peer pressure, or their repressive government or pseudo-Amish lifestyle makes juggling multiple profiles inconvenient. Regardless of the reason, there are just some people who only use Twitter and email to communicate. And when these individuals are ready to share more than the standard 140 characters with the Twitterverse, they've got a few different tools to choose from.

When we first reviewed Posterous, we called it a 'minimalist blogging service.' All you have to do to start blogging and sharing content on the service is to send an email to post AT posterous.com and it will automatically set up a blog for you. Now, however, Posterous is expanding its service and slightly changing its direction by adding a bookmarklet that puts it on a direct collision course with tumblr, the popular microblogging site.

Posterous is such a simple microblogging platform, it almost makes Tumblr look overly complicated. The Y Combinator funded startup is a bit of a mix between a blogging and lifestreaming service, with a little dose of Twitter thrown in for good measure. To start using it, users only have to send an email to post AT posterous.com and, within a few minutes, posterous will respond with the address for the new blog.
