liked the concept idea of the web-site with both females and males participating together to help sort out an answer, liked the way it was also designed and how it was organized and separated both the boys answers from the girls answer to come to a certain common goal or conclusion, sweepstakes, contests, gift cards, the integrated experience points, instant messaging on the fly, and the fact that the web-site is very fluid and addicting as hell, just a few things off the top of my head.
I joined when I was about 16 - 17 ish, people seemed to like the advice I gave, so I hung around. Oh and the gift cards were cool. Didn't know we got those until around 5k points or so ha ha. Back then they were 3K though so
