Twitter CEO Dick Costolo speaking at the conference Web 2.0 Summit in San Francisco, said that the collaboration with Apple Inc. would be more fruitful than expected. According to the head, after the public release of iOS 5 registrations iPhone and the iPad's social network Twitter for the first day has increased threefold. "Apple will become for us the corporate mentor" - said Costolo.

Twitter CEO also gave some statistics work managed by the project. Daily Twitter users publish on the service up to 250 million messages then a year earlier compared with 90 million and at the beginning of 2011 was 100 million. Thus one billion new "tweets" now appears in Twitter every 4 to 5 days.

No doubt twitter increased its traffic day by day beyond its expectation.
