That's a good point. There is a big distinction lost on a lot of people between "importance because I like it" and "importance because others like it". The DJ who plays the Electric Slide at your wedding because he like it is the typical example of a guy who can't see outside his own opinions of the world.

I'm not sure how I feel about facebook either (from a technical standpoint, I feel the same way every developer I know feels: "[homer voice] doh! I could have done that in a weekend!"). But given the way its become the sharing medium for a whole generation of college students, it deserves a lot of respect and attention no matter how you feel.
