Mostly because I believe i'm dead boring
You're wrong about this you know, and you're actually kind of the worst judge of how interesting or not other people might find you, because you're the only person in the world on your side of it. *I* find chatting to you here and in Steam interesting, so, bam, wrong, and you have to accept my testimony because you can't possibly know what it's like to be someone else and talk to you. You're not going to have any fun lengthy conversations without sharing a bit of yourself. So. Try it imo. You're not going to connect with everyone, or even more than half of everyone. Just keep at it, practice makes the world of difference.
