ReadWriteWeb

Rollyo is a simple way to "roll your own search engine". You can get started by choosing a few pre-defined categories - these contain a list of URLs that you can add to.

It gets a bit more interesting though if you add your own URLs though. From the homepage, click "Create Searchroll" and you can build a custom search engine.

Paris-based Lemonchik has announced Version 2.0 of their topic-by-topic aggregator, Guzzle. Do you...dig?

Guzzle's new backend, Nibble, has been rewritten from scratch. Nibble receives PubSubHubbub notifications and every story is automatically processed with Reuters Calais technology, adding rich semantic encoding information. There's also a new user interface, categories and archives and a magazine-like "extended view."

While social media is often touted as a great lead generator and brand management tool, it can also help bad coverage spread like wildfire. Last year, two disgruntled North Carolina employees made an in-store gross-out video where they tampered with Domino's Pizza orders. Despite the fact that the employees were fired, Domino's was dealt a major blow as the brand was tarnished and all efforts to recover were met with criticism. Video aggregator Yubby is about to launch a solution that helps startups mitigate the risk of brand-damaging videos.

When it comes to video discovery, the thrill of the hunt is only really fun when you're viewing more good than bad. You could scour your feeds for entertainment, but the fodder you'll file through is enough to feel like work. Tomorrow is a Friday, and we all know that you're going to mentally check out from your desk at about 1pm. With ReadWriteWeb's list of easy video aggregation services you can spend the afternoon curating your corporate videos, scouring for media clips or sharing amusing videos with friends:

News aggregation startup Thoora is celebrating its public release just one day after ReadWriteWeb's Real-Time Summit. In June, we wrote about the fact that CNN was hours behind Twitter in reporting news from Tehran. As real-time services continue to trump traditional media outlets, companies like Thoora have jumped on the chance to build a better news source. Since Thoora's recent demo at TC50, reviewers are already questioning whether the company can survive in what is proving to be a crowded space.

If you've ever created your own podcasts or home videos then you've probably got content sprinkled across YouTube, Vimeo and Blip.tv. As better video services arise, there's always that familiar debate: do you take the time to migrate your archives to a new service or do you embed multiple files into your site? Dutch video site Yubby creates a seamless solution for video display across 3rd party services. Rather than forcing users to embed multiple videos or links, the company lets users drag and drop videos from a variety of sites into a single embeddable player widget.

In a fairytale case of ask-and-ye-shall-receive, we issued a call for sports-related apps, and startup FanFeedr answered that call.

FanFeedr allows users to select topics of interest and find (hopefully) relevant scores, photos, news, videos, and blog posts. It also plays nicely with Twitter and Facebook. Their search function was buggy (we kept getting redirected to "all content" rather than info for our search terms), which makes it difficult to adjust the firehose of available information, but the concept is nevertheless intriguing.

In wake of the news of the FriendFeed acquisition by Facebook, we're faced with the real possibility that FriendFeed.com will be shut down for good. According to the press release, "FriendFeed.com will continue to operate normally for the time being..." In other words, it's only a matter of time before the site is gone for good. What is the FriendFeed community to do?

At one time, FriendFeed clones like Lifestream.fm and Socialthing! looked like promising alternatives, but neither of them offered the same rich and innovative features that FriendFeed does - the very features which made FriendFeed the standout service that it is today. However, there is one service that may have an opportunity to capitalize on the FriendFeed exodus: social media aggregator Streamy.

Silentale is a soon-to-launch startup whose goal is to consolidate your conversations and contacts from all the platforms you use including webmail, social networks, and even your mobile phone. Running as a software-as-a-service (SaaS) platform on top of Amazon Web Services, the oddly named Silentale will function not just as an aggregator, but also a searchable archive of all your web communication. While normally we wouldn't dare blog about a company whose product you couldn't try out yet (that's just mean), we just couldn't resist. It's been a long time since we've seen a startup this promising and we can't wait to give it a shot ourselves.

We've all seen a great deal lately of two trends: Personal website creation made simple (here's our favorite four resources of the moment) and social media aggregation services that pool all a user's streams and networking information.

Today, TinyChat creator Dan Blake along with cohorts Oliver Turbis and Joshua Gigg have announced the launch of a new freemium-model service that combines good-looking personal sites with users' existing social media data, and all in a mercifully lightweight format that's as easy to digest as it is quick to set up. Although the service, called Card.ly, is reminiscent of Retaggr or Chi.mp, it humbles the competition by delivering a simpler, more focused result. Blake et al. apparently understand the old adage, "Less is more."
