I definitely agree that there is a ton of institutional resistance towards forms of new media. I guess it's mostly a vestige of the idea of low cultuer versus high culture - which deserves a place in museums? It's sort of strange then to think about the fact that a lot of the stuff online is both created by and geared towards the upper-class (though obviously this is becoming less and less true). So why doesn't that translate into "high culture"?

On an art-related note, I realized today that one interesting 'art' website has never come up in discussion: You're The Man Now Dog!. YTMND is a really interesting site that features these sort of static web page art projects. You basically take a picture, add some text and maybe put in a sound file. Volia! Instant art. A lot of cool Internet memes come out of there. You should take a few minutes to browse around if that sounds interesting to you.

It's worth considering I think that the structure of a museum is only conducive to certain, highly centralized types of art that usually condense into objects. While I have seen exhibits that make use of interaction, computer processing, and projected images in museums, there obviously isn't much of a conceptual art presence, usually, unless it involves, again, objects. It's true that the work of many current conceptual and performance artists isn't something that can be fit onto a wall or pedestal, and you could advance the point that museums, since most people consider them to be bringing art of all sorts to the public, should do a better job documenting this stuff.
