Could be, I think a lot of real world dating starts with social situations that aren't explicitly about dating. Probably better that way, who needs the pressure of rejection or rejecting that leaves no room for other options.

It's a community with a dating subset to it.

Not everyone is vocal about their relationships, Ben, when they are fairly new.
I suspect many of us are cautious about publicizing of crushes, especially when first beginning to care about another.
What if this person isn't who or how they claim to be? What if we eventually meet and the chemistry is just Wrong?
Can I deal with public ridicule, or is it easier to wait and see?
Be yourself, relax, enjoy our little soaps, dramas, and hilarities, there's someone looking for exactly you! - just hasn't found you yet!

Was this originally a dating site? never really thought of it like that.

There have been successes, but I think the site has morphed into more of a solid discussion and support site. I've had loads of interesting conversations and met some really strong characters. The dating side of things has actually almost disappeared for me, - it's great to be able to talk openly with like-minders. But if you see someone you like, message them. Don't wait for them to ask you!
