What about Attaboy?
He often makes me laugh and seems generally calm and funny with that awesome avatar. Even with that rumor about the two of us spending 'sleepy time' together. And I can't be his friend cause he set it to private or blocked me or something.
And walsufnir? Seems always rather level headed and curious. Plus, can explain some things to people in a way they seem to learn about stuff. Although, I think he is heading towards a grave mistake. (But he might be rich, so why bother.)
Others too, but some have been posted already.
