Social network, neg
I've found some good relationships online. It was just finding personalities that mesh well. Usually calmer folks with a quirk who were a bit more based. We don't always see eye to eye to on everything, but we appreciate the company of each and enjoy similar hobbies.
As far as not seeing someone again, maybe in the work place, but offline can be like that. There are some folks who are nice, but I'm not crazy for their company. I just don't contact them .
