In Debian experimental would be a Steam compatible libc6 as well but when you build binaries and you want to share em then they would be all incompatible with pure wheezy. Steam began to ship a compat environment but they did it completely wrong. The bootstrap code requires a new libc6 and of course they don't use that compat files for bootstrapping. Absolutely useless code right now...
Basically wheezy is very interesting as it is the first multiarch Debian version. When you combine it with the backports I do for Kanotix Dragonfire which is wheezy based it looks pretty solid. I use of course latest kernel 3.8 and have got fglrx legcy 13.1, fglrx 13.2 beta 6, wine-unstable 1.5.24 and some others in my repo.
Steam worked since the beginning with Debian with my script. Just some stupid apps needed a few more tricks like Unity of Command (there you have to extract libc6 again in the program folder) or sometimes they have got weird dependency checks. I dont remember the demo right now, but no game should require ia32-libs, that's just wrong when the system is multiarch. Ubuntu uses it as meta package now but it will always be wrong when you check if that package is installed.
I can't believe that people actually use Debian. I installed it once, and I remember thinking to myself "Wow, I remember this stuff. But, I want to use the new stuff!"
Somehow, I suspect that those KDE trollers we have around here(The ones who constantly complain about bugs) are using Debian - Martin Graesslin has generally(Not aimed toward Debian) addressed this (though, I don't have the link, sorry) about people who seek to have bugs fixed but they're using too old of a version to get their bug fixed. The KDE Devs only fix so far back. I would too.
It's so nice that the Debian installer has progressed beyond 2001 and now supports WPA/WPA2.
Its been true that the installer did not support wireless network connections for doing netinstalls until now. You always had to hook the machine up to a router with an Ethernet cable to do a netinstall. About time Debian got this missing feature installed.
However its not really a good idea to do a netinstall over a wireless connection as the connection is not as stable as an Ethernet connection, but soon you can if you do trust your wifi connection.
