MonkeySpace (run by Monkey Square – yes, it’s a little confusing at the moment) is:
is the official cross platform and open-source .NET conference. Want to learn more about developing for the iPhone, Android, Mac, and *nix platforms using .NET technologies? How about developing games or learning more about open-source projects using .NET technologies? MonkeySpace has provided an annual venue to collaborate, share, and socialize around these topics and more.
I’m hoping a few more go up, as there are some I linked to before which I really want to see.
As Monkey Square is a non-profit (tax deducable if you are in the US, i would assume), if you find the videos interesting, please donate, so they can do more of them.
