Google Inc. is adding 625,000 new users a day to the Google+ social-networking service, which may total 400 million members by the end of next year, according to independent analysis of its growth.
The site’s popularity has accelerated in recent weeks, with almost a quarter of its total user base joining in December alone, said Paul B. Allen, the founder of Ancestry.com Inc., who tracks the numbers as Google+’s “unofficial statistician.”
