i don't have time to read what everyone has said here right now, but just wanted to chime in - it's definitely interesting to see what the line is on twitter accompanying the actual headline when you click on the link. it basically says - hey we should re-examine this guy who's just been wronged by his band.
that said, i think he's both, except biggest jerk is way out of line, just like he's not the most misunderstood genius either, not by a mile - but they didn't claim he was. on the other hand, there are tons of way bigger known jerks in rock, he's not even half way up the ladder. someone on facebook said maybe the headline should be changed to something like -
Rock's garden-variety jerk or misunderstood genius?
