Doesn't sound cool to me. The most interesting relationships I have are the ones where there is not a huge overlap. They are more interesting.
I was a Meeteor user, albeit an inactive one -- I don't remember receiving emails engaging me or asking me to come back, so I forgot about it over time. That said, I signed up in the first place because this is indeed a pain point for me and many others I know. At the time, I had just moved to a new city and was having a hard time making friends (basically, I didn't have the balls to attend classes, meetups, etc. by myself) so I saw products like Meeteor as providing a great solution. Even now, I would love to expand my circle of girlfriends but in an industry filled with men, it's been hard to find like-minded females who happen to share similar interests.
