I'd hardly call him unattractive. Classy glasses, a well kept appearance (which can be challenging with a thin mustache)... a slight overbite is about all that might be considered unattractive; but his attitude and voice more than make up for it.

Almost speaks more to the accepted definition of "attractive" than the streamer.

I haven't looked in awhile, but when I used to watch dota streams the top four or five (by viewer count) were always extremely attractive Eastern European and Russian women. They were better than average players, but not good enough to command that kind of attention.

Lol, this was exactly who I thought it would be.

And his voice? Lots of the top youtube game reviewers arent exactly attractive physically, but they have classic radio voices. Totalbiscuit and most all of the yogscast fit the profile.
