> there is an 8 year time gap between the release of 7 and XP Which is why the metaphor is off. Safari+WebKit and Chrome+Blink are being developed in parallel and competing with one another. They're not two releases in the same product line where one is the dead forebear and the other a successor. > it's not terribly pedantic to insist that Windows 7 is, in fact, built on top of Vista and not XP What? That wasn't the topic. None of this is relevant. The topic is which engine Chrome is using. Explaining that Chrome doesn't use WebKit isn't pedantic. However, when someone does explain it, for someone else to appear and point out that the engine it uses is forked from WebKit—a nugget of information that changes nothing about the discussion—is pedantic. I think you're responding at this point for the pleasure of feeling like you're having a conversation, or you're still misinformed about which browsers use which engines. WebKit is not Blink, and Chromium is using the latter, not the former. That's the whole point of this entire digression.
