It turns out Google+ is a virtual ghost town compared with the
site of rival Facebook Inc., which is preparing for a massive
initial public offering. New data from research firm comScore
Inc. shows that Google+ users are signing up — but then not
doing much there.
Visitors using personal computers spent an average of about three
minutes a month on Google+ between September and January, versus
six to seven hours on Facebook each month over the same period,
according to comScore, which didn’t have data on mobile usage.
