Spacebook

Spacebook (at spacebook.wikia.com) is a wiki-based social networking site founded in late 2009. Its name is a pun on Facebook, the extremely popular online social networking site. Spacebook, being a wiki, allows people to edit each other's profiles. A profile on Spacebook is obviously just a user page, Spacebook being the MediaWiki-driven wiki it is. Very few people have set up profiles on it.
