Google Plus has been out for just three weeks and is expected to hit 20m users in the next few days. Not bad considering it was at 10m when we wrote this story last week – that’s a growth rate of 750,000 new users per day (almost as popular as our Twitter account). Don't get too excited though, the growth of Google Plus has slipped from 1 million per day, but that's without any Google channel marketing and comes purely from invites – impressive.
