Microsoft founder Bill Gates has officially joined Twitter and is amassing followers quickly.
The 54-year-old Gates, who stepped down from full-time duties at Microsoft last year to concentrate on philanthropical efforts, had more than 150,000 followers in his first 13 hours on the site. As of this writing, he had nearly 200,000.
Gates’ first message was “Hello world,” a common phrase used by computer programmers learning a new language.
There have been numerous Gates imposters on the site, but the new account is verified as official.
Gates, who still serves as Microsoft’s non-executive chairman, says he plans on “sharing cool things I’m learning through my foundation work and other interests” in his bio.
