My insinuation is along the lines of looking the part (in a stereotypical sort of way), but not being able to deliver.
Eh, I think all music publications are going to tend towards what's "popular" even when what's popular really sucks, but I wouldn't write most of these folks off just for how they look. Again, lots of really interesting stuff being done in genres that are only slightly off the beaten path.
That said, to my point above as well as I think what you're getting at, I do remember when that nu-grunge thing was starting to happen - god-awful bands like Puddle of Mudd, Nickelback, etc - and BP was all about those dudes. There was like a four page story about the guy from Nickelback which made me roll my eyes.
It was when the second wave of nu-grunge happened that I cancelled my subscription. There was this unbelievably mediocre band that I won't mention, they had like one hit that cracked the top twenty, barely, and there was like, a two-page interview with their bass player. BP tried to use all this flowery language about "fitting the song," "catchy simplicity," and "being tasteful," but they were really clearly just trying to mask the fact that the dude could barely play his instrument and that quarter notes on the root were about as much as he could handle.
So yeah, I think I get where you're coming from.
