Not too many people on PC are versed enough in ricing to care about it, so it isn't surprising. It's weird to actually give a damn about it now because when I see people post desktops on facebook and everyone is like "nice" I'm just sitting here with boatloads of ammo ready to criticize them for it.
The only ricing I see like that is on /g/, and outside of that, the only ricing I see is the occasional rainmeter. So it's nice to see something other than rainmeter being posted.
