I know this has been requested before but it hasn't been implemented and I don't know why. There are website like Steam Card that create Steam Gamercards similar to the Xbox Live ones that we use for the profiles on this site.

Pfft, blasphemy, get rid of the AIM link, nobody likes them anyways.
I don't think Gaming Stuff is a good idea. You need an account, it's only for TF2 (at this point anyway) and it's too long compared to the Xbox Live and PSN gamercards (while Steam Card is about the same length as the others).
