Arrington has said that many who attended this event were friends of his. I'd think it wouldn't be too difficult to sense a strange vibe and that something unusual was going down. I've seen Arrington make some big claims (last.fm handing over records to the RIAA (unsure if that was resolved)), but these are pretty damaging accusations, and you've got to realize that more than just page views, there are a few other things riding on this recent piece -- like the friendships of those he's accused of colluding, general respect among the angel/vc community and beyond. That coupled with this post, with a tl;dr of HE's WrONg ANd I WanT TO BE AbraSIVE AnD NOT PROviDE REASONABle LEVel-heaDED ARGumEnTS, makes me side with Arrington for now, although Fred Wilson's post does make a lot of sense.
