Yesterday, I raked Mashable’s Ben Parr for his assertion that Apple’s then yet unannounced mobile advertising platform posed a credible threat to Google. Now that Apple has announced iAd, and seeing how Ben’s rumor reporting was right about it coming, I circle back for a postmortem. Simply stated: I stand by my assertion that his sourcing was weak and that he didn’t support bold assertions that Apple’s still unreleased mobile ad platform is way ahead Google’s.
