I guess my thing with Bonnaroo last year (the only year I went) was that I only went for phish. There were a few other bands on the lineup that I looked forward to seeing (Snoop, Galactic, Wilco, Toubab Krewe) but for the most part I got the vibe that the fest was going really "indie" (TV on the Radio, Mars Volta, Yeah Yeah Yeah's, MGMT, of montreal, Animal Collective, Grizzly Bear) - That type of music isn't bad, its just really not my thing.
This band passion pit I saw was terrible though. I didn't understand how people considered it music. And all the little indie-hipster kids were eating it up.
Like I said, that was my first year at bonnaroo so this may be unjustified but, I think it's changed a lot. Looking at the lineups from 02, 03 - I dunno, I think I would have much rather wanted to "suck it up" and deal with any sort of hardships with lineups like they used to have.
