Geeksphere is a collaborative linux blog built around a small IRC-community. I am taking part as an active contributor. There are a bunch of geeks writing about all kinds of stuff like net activism, linux, projects they are working on, howtos, aso.
The blog is frequently updated whenever somebody feels like writing about something more or less important. The frontpage contains aggregated content from various web2.0 services and places where the users are active.
