I'm conflicted.
On one hand, I agree with his rant on other tech journalists / editors, but on the other hand, what he's essentially saying is, bias on his part is okay, or even expected, if the company he's writing about is one that he's investing in?
Given how influential techcrunch is, are you supposed to cross check all the companies in his portfolio, figure out if the company you're reading about is a competitor and then adjust for bias as you read? Isn't there a huge difference between being loosely linked to Google / FB and investing in a company?
