This is something I personally brought up with them after being gifted a copy of Pandora from the developers, it was all highly confusing as you had to specifically click the Linux link in the platform list otherwise you would be buying the Windows version and it didn't actually tell you this anywhere. They are another store who needs to note Windows and not PC though, you know how annoying it gets to see that.
The numbers don't look very good overall if you directly compare it to Windows, but like with everything Linux I am personally pinning my hopes on Steam Machines & SteamOS giving us the boost we so deserve. We aren't that far off Mac numbers which is encouraging at least.
Valve team is working on a new tool to facilitate game developers on Linux. VOGL is an OpenGL tracer/debugger which will be used to analyse OpenGL calls. VOGL was announced in the Steam Dev Days conference. The debugger is being developed on Linux natively. It will be an open source project.
Whether or not you think games are important for Linux, the stone cold reality is that they significantly drive mainstream interest in any operating system. As I wrote in the feature for LXF179, Linux: the Future of Gaming, this was a lesson Gabe Newell learnt back in the early 1990s while working for Microsoft – and it changed the direction of his career.
I just posted a SteamOS ISO that can be used to install SteamOS on non-UEFI systems. Thanks to directhex and ecliptik for their work on Ye Olde SteamOSe - this incorporates many of their changes. Dual-boot and custom partitioning are now possible from the "Expert Install" option.

If you've never tried Linux or are looking for a new distro to try then check out Linux.com's top 7 distro list for 2014. If beauty is what you seek then Bodhi is a good choice as it has modified the Enlightenment window manager into something a little more manageable. For Ubuntu users there are two variants you could try, Xubuntu for desktops and Lubuntu for older less powerful laptops. For the security conscious there is TAILS, which automatically routes traffic through TOR and constantly deletes any tracking info from local storage as well as being specifically designed to run from a bootable USB drive. For the geeky parents out there, or for those looking for a very simple to understand distro is DouDou. It comes preloaded with an array of childrens learning software and Dan's Guardian to somewhat limit internet sites of a nature unsuited for the very young.
