@sunnysideup - I agree, this is a good idea but it really doesn't seem necessary. After all, plenty of dating women have found their match online by just talking to each other.
Talking to the person you are matched up with is a good idea before that first meeting. Even if that first meeting is just a bike ride or a hike.
Personally, I wouldn't want to spend time with someone just because we like the same activities...there has to be much more of a connection on many different levels.
