[quote=@Awson] Why do you insist on the Spidey Avatar? You seem to be going up the Old Grump route, and I gotta say that the tired 60's Spider-Man meme (which is mainly for 12 year old's) doesn't quite fit what you're going for. Besides being lame in general. Unless, of course, you have a dead friend who was really into that meme and you have it as your avatar in his or her memory. In that case I take it all back and I apologize for being so abrasive. [/quote] I started using it because I thought it looked silly and after awhile I got too used to it and just kept it.
