I think part of this issue could be the making friends part. The initial meet is the common interest here, then we have life, etc. People become friends, talk about work, the latest movie, etc. Then this just becomes another part of everything. I guess that's how a relationship should be, but at the same time, the fantasy of it here keeps this part focused, while the reality then that you're people with lives might turn many hopefuls away. The dating scene is such a game these days to begin with, and mostly a losing one, so can't see that just because someone has the same interest here, that it would be much different. Some get lucky.
