Qweb library has been released this night!
Qweb is a collection of puredata python objects that performs web research to find texts, images and videos to use in puredata.
It supports twitter, flickr, youtube, jabber, RSS, wikipedia, and general web elements like images and pages.
It's pyext based and should work on all platforms.
I already uploaded it on http://puredata.info/downloads/Qweb/
