Ok, they tell me I have to follow their rules and you will be more likely to respond so here goes nothing...
Hobbies? Yes, I have them. They're fun. That'd be a good thing to ask about if you want to talk.
Goals/aspirations? World domination... and stuff.
What makes me unique? My mom says so?
My taste in music? Good stuff. Most genres have stuff that rules and stuff thats crap. I like the stuff that I think rules. And sometimes its fun to laugh at the crap.
Basically, I was here before and had some big long thing talking about how everyone has their quirks that makes them who they are and how when you find someone with just the right complementary quirks, sparks can fly. I still believe that. I also believe that its hard to be able to figure that out reading some silly thing someone posted about themself on some website. Call me old fashioned, but the "getting to know ya" stuff, for me, is still better without typing. This can be a good jumping off point, though. So who wants to jump? ...Bueller...Bueller...?

The longer the description the more likely I'll get responses? I thought the longer, the more likely people will not want to waste their time reading such a long description.
It depends on the person, the situation, and what seems appropriate at the time. Anywhere from coffee to a last minute trip to Disneyland. Who knows...?
