Basically, a website would provide a guerilla-style marketing outlet and fill in the void (rather than having the void filled with rumors and half-information). Since Adam seems to have a grass-roots sort of fanbase, it would make the most sense. Also, if he's targeting the college circuit, web is your best advertising/ marketing medium. It's a shame not to make the most of the opportunity.
The problem with Myspace is (a) it doesn't get updated very often, and (b) while the friends are nice, all of those comments reflect directly on Adam-- if it's his official site, it gives the impression that he approves of all the content that's there. Yes, we all understand what Myspace is, but to newbies that are just checking it out for the first time, there could be a less-than-positive reaction.
...sorry, Marketing-Geek-Speak just slipped out. You can tell I've been doing this stuff too long. ;~)
