i disagree, respectfully, with you, for precisely the reason you claim to dislike the 'rubbish.' i think a very large proportion of fandom suffers from some degree of social anxiety. i would say that i do (in fact, making this comment is terrifying, and i don't even know who you are).

but the fact that a couple of people have created imaginary foibles for a famous person not only humanizes him -- makes him seem more like someone i might know -- it also provides an outlet for people like myself and others in fandom. we can project meant-in-jest personality quirks onto someone that we admire, while at the same time celebrating our slightly-manic obsessions with him amongst ourselves. we're both de-celebretizing him and making him the focal point around which we gather.

so while i understand that you would like people to take social anxiety disorder seriously, i don't think that jensenvention made light of it. in fact, i think the site and the people behind it struck a very resonant chord amongst a large proportion of SPN fandom, precisely because it combined some cogent, real life experiences with one of the central reasons we're on the internet in the first place. cute boys.
