A lot of people didn't bother upgrading from the 50D from what I read when I was looking around. It seems that people like myself, that had the 30D or older moved to it. People that had the 40D or 50D generally seem to move to the 7D or 5DmkII, or even higher if they had the dosh/inclination.
I don't think the camera really dictates what you shoot, unless of course you're a pro, but then chances are you'd go for a pro body. I've seen people doing wedding photography with it as a second body (using 5DmkII as main), wildlife, sports, etc.
There really doesn't seem to be a lot around about it as you say, but just look at info for previous bodies as it's just an upgrade, but as I say, others prefer the 50D body as it's more robust. My 30D feels far more substantial than the 60D and the 60D does feel a little more 'cheap' when you first use it. Also I found that you need to be far more accurate with the 60D over older versions as the higher MP is less forgiving with camera shake, etc.
It took me a day or two to get used to the layout, etc, as that's different to the 30D. Have a look on youtube as there are videos on there showing you what the 60D can do. The flash control is quite nice
