Well, there goes Google+. @keithhannon finally got his wish. It was better there…mostly because most people were on another thing. It would have been interesting to see how the G+ features would have held up under critical mass. Oh well. We should all have out own social spaces that we control anyway.
I would be remiss if I didn’t point you to Killed By Google to take a gander at alllll the things that have met untimely ends. Though, to be fair, many of those products/projects were rolled into things that still exist.
