One of the cool things I in particular like is the ability to download the Hubblecast in various (very) good qualities. I personally think that it's crucial that professional astronomers themselves actually participate in producing outreach material of this kind, since so much science is going on and non-astronomers only get to know very little of all the exciting new discoveries and beautiful images.
Encylopedia Internetica writes: Ars Technica is running a feature on Citizendium, Wikipedia cofounder Larry Sanger's attempt to build an online knowledge repository that avoids some the 'serious and endemic problems' Sanger has seen with Wikipedia. His decision to launch Citizendium came as a result of the issue with John Seigenthaler's Wikipedia entry. 'Sanger had hoped that Wikipedia would clean up its act, and he was all but certain that the encyclopedia would eventually put an expert review system in place. After Seigenthaler's call, Sanger found the Wikipedia community's response "completely unacceptable" and concluded that they were no longer able to change in important ways.' The feature also looks at the Citizendium 'expert' system as well as the editing and article approval process.
