I think that's all pretty true. The last couple times I went, I mostly camped out in a few Devrooms that I was more interested in (for the most part) and it was a much more pleasant experience than trying to constantly hop from room to room. You can always watch the videos--although the reality is that most of us don't really get around to it in general.

I wouldn't put off newcomers though. While people do connect with those they already know, generally all groups are friendly and welcoming to newcomers, too.
