Online friends

[32bit-RedMage]

I am completely aware that I sound like a moron when I ask advice like this, but here it goes anyway;

How do I make friends online ?

I don't have any problems socializing in real life, but it's a whole different story online. When trying to meet new people n' stuff the same problems always emerge.

-Can't find someone with similar interests.
-If I do find them, then the conversation comes to a halt, and no matter what i try to say I don't get more than a "yeah" or "meh" reaction from the other person.
-I always seem to give them a wrong impression, and they end up hating mer or ignoring me

I ask you guys cuz' you're all pretty cool guys and seem to be pretty good at this. I mean.. you're always talking about people you meet online and long distance relationships and stuff.

What should I do ? What kinds of sites do I visit? (I seem to be frequenting the wrong ones) Any advice ?

Thanks in advance!
