    Browsing through that list brings back memories and it reminds me we’ve been at this a long time now.

    That remains to be seen.

    Thanks, Barry. Not surprisingly, many of our resource links in the list go back to SEL. Deciding what should be included was tougher than I initially thought. Even figuring out technically what’s an algorithm update can be tricky. Caffeine was certainly important, but it technically wasn’t an algorithm update. Leaving out Panda would’ve drawn 100 complaints, but it’s not clear Panda is integrated into the main algo (I think Vanessa’s “platform” description makes sense – almost like a lab sitting to the side that feeds into a ranking factor).

    I can only say that it was a lot of fun to dive back into the history, and I’m looking forward to adding to the list and trying to keep it current.

    They left out the Local Map User Interface update that removed Reviews from non Google sources from the local results and Places pages.
