TechCrunch doesn't need puppets. It has its fans. I'm not a big TC reader, but I like all the people I've met who work at TechCrunch. They're all genuinely nice folks (though Arrington has the troll gene, so sometimes he goes overboard and picks on someone smaller than him, which is rude and in poor form...but I don't mind when he picks on Google or Yahoo or MS or anyone who's accepted more than a few million in funding).
Agreed. Arrington has a huge media empire. Perhaps he trolled and spammed back when that all started (though I'm nowhere near certain of that, either), but now he's got nothing to benefit.
