Steam Dev Day talks now publicly available
Valve has released videos of 28 presentations made during its Steam Dev Days conference. The big headlines were mined from these talks as they happened, thanks to Valve's admirable openness, but there's plenty of detail worth absorbing, on Steam Machines, Valve's economics, user generated content, and virtual reality. The VR stuff is said to have been particularly impressive. There are 28 videos, so go have a browse.
Thanks, Destructoid.
