That’s a lot of people:
In kicking off Twitter’s Chirp developer conference, the company finally revealed its long mysterious registered user number, and it’s surprisingly large (based on some prior outside estimates): 105 million, or to be exact, 105,779,710, according to a slide showing behind co-founder Biz Stone during his opening remarks.
The growth’s not over either — Twitter says they’re still adding 300,000 users per day. Moreover, as many have speculated, most of Twitter’s traffic — 75% of it in fact — comes from third-party clients and applications.
