I see your point, and I don't mean to beat you up about it. I guess my only other question is how can you trust a word they print? With the legal standard of libel so high for public figures, and their tendency (in my opinion) to willfully misrepresent, it just seems like a waste of time - like reading the National Enquirer at the checkout line for updates on the whereabouts of Bigfoot. I'd rather read a novel or catch up on Breaking Bad.
I also don't think Valleywag has a monopoly on looking critically at Silicon Valley and startups like Prim. I've seen plenty of critical items on startups of that nature in both blogs and mainstream tech reporting, many of them featured prominently here on Hacker News.
The reason Valleywag has this rep as a critical eye on S.V. is because it is uniformly, hyperbolically negative. Check out some of their now embarrassing past coverage on SpaceX and Tesla. I'm guessing they don't cover them much anymore.
Valleywag is the web-embodiment of a bitter, know-it-all drunk heckling CNN at the bar all day.
