Twitter now delivers an astonishing 350 billion tweets each day, the company said on Friday. ”Delivering 350 billion Tweets a day is a terribly fun engineering challenge. But, it doesn’t capture how passionate our users are,” the company said from its official Twitter Engineering account. Coincidentally we’re sure, the news comes just one day after Google bragged that it had amassed 10 million Google+ users in just two weeks, and that these users collectively share 1 billion items each day. Google+ has quite a way to go before it is anywhere near as popular as Twitter, of course, but it’s certainly doing well for a 2-week-old product.
