There is a proposal to create a Raspberry Pi Stackexchange site here:
http://area51.stackexchange.com/proposa ... spberry-pi
This isn't my initiative but I think it's a brilliant idea and am happy to spread the word! And I'm sure there's a few people here with stackexhange accounts who could lend some weight. The initial proposal has been accepted and now the site needs a few more 'likes' to move to the beta stage (in which a site is created).
There is a chance the group scope could eventually move to encompass all micro-computing or possibly embedded devices. But the proposal itself is based on Raspberry Pi.
In any case, I just thought I'd pass on the link to help everyone out. Share and enjoy etc!
