I run a forum dedicated to the Omega Man film [www.theomegaman.info] and out of the 21 current registered friends and members, only myself and one other person actually owns a BluRay player. I have spent countless posts trying to convince the others how superior BD is over DVD to no avail. I know this is a small focus group, but still 2 out of 20 perhaps represents the fact that there are still many people that do not know the advantages of BD over DVD.
On to BD Live, I myself have a few discs with this feature that I have not even bothered with, why? Because of the fact that when I want to sit down after a long day at work, I want to watch the movie, not sit there and play games with it, chat live to others, download ring tones, etc, etc, etc. I think many people don't really care about it, myself included to some extent.
