It actually requires you to have a larger amount of libs on your system and can make things (unnecessarily) more complicated. So if you have less than 4GB RAM, I only see disadvantages in installing a 64bit OS. Or what advantages do you see? I see none.

32 bit apps can access a full 4GB virtual address space on 64 bit OS's.

If the applications you need arent compute heavy then it probably wont matter, but it is still an advantage of 64bit over 32bit that applies even at smaller memory amounts.

Many people such as myself have Steam detected as being run on Ubuntu, when in fact it's just a Ubuntu chroot. Some might even have configured a dual-boot setup just for Steam to minimise problems.
About 2-3 weeks ago I switched to running natively on Debian, but I've had a few issues in doing so. Occasionally, Steam updates break my setup and I manually need to fix things (such as updating my Steam launcher wrapper script to include additional environment variables, changing from running the beta release - which I didn't even know I was still using - to reinstalling as stable, etc.).
Until Steam actually officially supports a larger number of mainstream distributions such as Debian, Fedora, OpenSuse and Arch, these numbers won't mean much. As others have pointed out, it doesn't help matters that Ubuntu has been supported by Steam from day 1 so people might have chosen Ubuntu when they normally would not have.
It still uses the Linux kernel and GNU userland, it's still a GNU/Linux distribution.

Steam has a bug in it that would make it difficult to support Fedora outright. Some of the libraries they used request both write and execute permissions on the same heap memory mapping. This compromises the system's security, and the default SELinux setup will have none of it.

Dont have fits over 32 bits
I have a gifted laptop from circa 2005 with an AMD Sempron processor (32-bit, 1 core), 512MB RAM and a 4200rpm 75GB IDE hard drive. Needless to say, Windows 8 isn't much of an option here. However, I just installed the new OpenSUSE 12.3 on it and the machine is quite usable (so long as you don't want to run lots of programs or browser tabs at once). In fact, I can run XBMC on it and its ATI (yes, ATI, not AMD) 200M (X300) graphics. It can play back 720p video files too - granted with no video acceleration and just about 100% CPU usage, but it works! Web browsing, Marble, Google Earth, Eric5 IDE and python coding... I can even use WINE to run games up to circa '98/'99 like Dungeon Keeper II and Half Life.

Please don't start asking people to kill off support for 32bit just yet. Why, it was just last year Linux killed off 80386 support! :-) Besides, there's a bazillion embedded controllers, including x86 controllers, kiosks, ATMs, etc. that are 32 bit that Linux needs to run on.
