Twitter Claims 105 million Registered Users

"Twitter has more than 105 million registered users, co-founder Biz Stone said Wednesday. The announcement, at the micro-blogging site's Chirp conference for developers, marked the first time Twitter has announced it number of accounts. The tally - 105,779,710, to be exact - is significantly more than outside analysts had estimated. The company also says it's adding 300,000 accounts per day, with much of its growth coming outside the United States."
