We agree to disagree then. I liked it much better with less people, anybody that went pre-2004 will agree on this. The ability to see more, and to see more of, the artists was one of Coachella's big draws, now it's more like ACL or Lollapalooza. Way overcrowded, less art, less comfortable.
The "vibes" you speak of are a personal thing sure, but the reality is there were too many people there. While you had a good time and good views, not everyone was so lucky. The reason, just too many people.
