Marty illustrates (quite literally) the problem with the Web 2.0 trademark.
Marty argues, as I did before, that the mark is generic and thus unprotectable. He points out though that this was not just genericide, but "self-induced genericide".
Before all of this happened, Alex realized the unifying theory of Web 2.0 is harnessing collective intelligence. This suggests to me that 1) the collective intelligence here is that Web 2.0 should not be protected, and 2) any brand / buzzword / etc which needs countless posts trying to figure out what it really means isn't really marketed and positioned too well.
