I've never met Arrington, so whether he's nice or not doesn't really apply to me. I also don't own a startup, so there's no conflict there. My personal beef is that TechCrunch is a 'serious journalistic entity' when they get documents leaked to them, but the second people start trying to hold them to the standard of real journalism suddenly it a blog. It's difficult to pinpoint, but there's something two-faced about…
Sure it does, if you've read his articles. Obviously most of the people who complain about him in comment threads have not met him in person. The reason they dislike him is that he uses the same un-ingratiating style in his articles.
When he reports something he's heard, he just reports it, without the usual boilerplate disclaimers that it's just a rumor, or pro forma protestations about how he hopes it's not true, or most dishonest of all, waiting for someone else to cover it, and then covering that coverage. This sort of sanctimoniousness is so universal in established media that it seems shocking when someone just skips it.
Speaking of intellectual honesty, it seems hypocritical to me that you're willing to accuse TechCrunch of "outright fabrication" and "baseless speculation" and the best evidence you can produce is a 2 year old guest post by a Stanford student.
If you have any examples of "outright fabrication," let's see them.
