Ever notice how some people are a little, ah, delusional? For example, some folks were telling me recently how Google’s social network Google+ usage was going down and the site really wasn’t that popular. Seriously. Clearly these people have been under a rock, or perhaps too besotted with Facebook, to notice that since Google+ opened its doors to everyone, its growth has been nothing short of explosive. Indeed, Google+ made it to 50-million users faster than any other social network.

According to Paul Allen, founder of Ancestry.com, a leading genealogy site and Google+ unofficial statistician, “Google+ likely crossed the 50 million user mark. And since being opened to the general public (over age 18) last week, Google+ has been growing by at least 4% per day, meaning that around 2 million new users have been signing up each day.”

To be exact, it took Google+ 88 days to hit 50-million users. MySpace—remember them?–took 1,046 days. Facebook, with 1,096 days, took even longer.
