Google+ Now Has 20 Million Users

And it only took three weeks!

After an explosion of viral growth and a period of somewhat slower (but still incredibly fast) expansion, the three-week-old Google+ has reached 20 million members, according to data from ComScore, which bases its estimates on a “global measurement panel” of two million web users. (Still no data on how much time people are spending on the new social network, though.)
