I'm surprised at the creative uses made of the various new "Public
Services" like Facebook, Wave, Twitter, Google Apps/Docs/Calendar,
Blogger/Wordpress.com, Wikis, .. and so on.
One instance is in mathematics. Sagemath: http://www.sagemath.org/
uses several:

http://planet.sagemath.org/
http://trac.sagemath.org/sage_trac
http://wiki.sagemath.org/
Each has a different focus, yet the total ecology seems coherent.
There are even tools available to integrate one "post" into several of
the sites. A tweet can appear in linked in and in facebook with
little difficulty.
Sure gonna make my homework easier come next semester!
