eschnou and alrdw in Belgium, the folks at storytlr.com, which was "not a startup, just a fun project" who had been offering their interesting social media aggregator as a service, decided to fold up their tents at the end of 2009, and as a sort of parting gift, released their codebase under the Apache license, as they had planned to from the outset.
storytlr, written in Javascript and PHP, was inspired by Loïc Lemeur's call for a "centralized me", and allows the aggregation and streaming of content from Delicious, Digg, Disqus, Flickr, Google Reader, Identi.ca/Laconi.ca, Last.fm, Picasa, Qik, Joe Random RSS Feed, Seesmic, StumbleUpon, Tumblr, TwitPic, Twitter, Vimeo and YouTube favorites.
Entries can be "mashed up" into stories, as well, and it seems easily customizable in a variety of directions.
Installation is pretty straightforward, although it does not seem at all to want to live anywhere other than a root directory: I need to fiddle around with the rewrite rules to get it to live in a synthetic subdomain. You'll need PHP5, plus mcrypt and curl. Handy tip: set "debug" to 1 in the config.ini file when you start it up, or you'll likely be looking at a blank page and scratching your head for a little while.
The initial drop of the sources is at http://storytlr.googlecode.com/, and it's well worth taking a look at if you're interested in this sort of thing...
