OpenData Q&A at StackExchange

StackExchange have launched a site for open data at:

http://opendata.stackexchange.com/

questions about webid, the read write web and open data in general ....
please feel free to add relevant links to our wikis ... I will try and go
through to see if there's anything in there already that may be helpful.
