I remember a beer commercial talk about "relationships". It said that it can last a lifetime or just the time it takes to finish a drink. In short, I think the expectation to meet "the one" (if that exists at all) on-line is too high. It should be about just meeting new people that we find interesting and let things happen naturally... in person.
You have to be open, able to hold a conversation and quick to smile. A pet peeve is flakiness so hope that isn't you. However, if you want to just meet for a drink and see where things will go, I'd love to meet you.
Also, I'm an ENTP (bonus for those who know what this means and double bonus if you know yours!)
