[about collection copyrights:]

There's a little more to it than that: copyrights apply to "creative expression", and "selection" of what to present is a creative act specifically recognized (see Feist v. Rural).

Ok, but neither Bomis nor anybody else can claim a collection copyright over Wikipedia in this sense, since nobody, and certainly not Bomis, actively selects articles for presentation in a manner that could be called creative expression. Or maybe: we all own tiny bits of the collection copyright in this sense, since we all occasionly reject articles.
