An official group is yet another milestone to having Steam on Linux. Also, there's a prominent `Join' button for them early adopters :-)

Right, but this doesn't guarantee beta access, nor does it confirm anything we didn't already know. I'm not trying to be prickly, I just don't see the point of this submission as it stands. If anything, the title should have been, "Join the Steam for Linux Beta Group" or something along those lines.

And if a million people join the group, they'll know they're onto something.

They already know they're on to something. If Gabe's worst nightmares about Windows come true, Linux will be his only refuge.

Yes, but unless they can convince large publishers that writing games for Linux is a good idea, it's not much of a refuge, is it?

Having a hundred thousand people sign up for his Steam group might be enough to get the ball rolling that way, though.
