This seems to be a good opportunity to waste some time, shoot the shi*t, and maybe get to know a few different personality types. Many of my friends have spent a good portion of their lives on OKCupid, so I'm thinking that there may be something to it, and I figure that I might as well see what all of the fuss is about.
I'm also blatantly ignoring all of the aspects suggested for writing one's own description, since I'm just that kind of a rebel and free-spirit :-). What would probably be good to know about me... I'm pretty much honest. I'm willing to justify and explain what I do and what I mean. The mysterious "guess what I'm thinking" attitude is cute or intriguing, but only when it's playful. Anything important, I'd prefer it to be up front. I'm also not one for holding secret resentments around. I think that talking about them will get you into fights, but so will the final eruption once the reality can't be ignored anymore. Tact is temporary, honesty lets you get things understood. Hope that's not too much of an overload, but at least that's fair warning :-)
