Right on schedule (ahem), Valve has begun requesting applications for the first Steam for Linux beta test. There are only 1,000 spots available, but the company is looking for "experienced Linux users" only -- presumably, ones that will be better at debugging than spilling zombie brains. So, if you've got a rig running Ubuntu 12.04 or above and decent Linux knowledge, head to the source link to register your interest.
