I was gonna say, the more appropriate question here would probably be "Does anybody even know who he is?"
Anyway, I don't know if Ani Difranco is worth a flying rat's ass (I suspect not), but w/o Woody Guthrie, there would likely be no Bob Dylan. So for that, I say "the guy couldn't have been that bad."
There's a "song" (poem more like it) on The Bootleg Series "Last Thoughts On Woody Guthrie"
That's my contribution to this thread. Oh, and Dylan rocks!
