The website fotonautpedia just lauchned. Tries to be a wikipedia for photos. So far the photos there are quite nice, also the interface (although its a bit buggy..)

My new favourite application has launched the beta of version 2.0. Zotero is a firefox plugin, which helps you to collect references to scientific literature easily (read an old blog entry by me here). Version 2.0 it makes possible to synchronise your library to the web in order to access it from any computer with internet access. At the same time sharing your library is possible and also to follow other peoples libraries.

Zotero 2.0 is still in beta, so regular backups are recommended!

Here's my Zotero Profile, as well a Digital Media Bremen group.
