ReadWriteWeb has a handy crib from the Twitter Chirp conference (at which our own Chris Thorpe has demonstrated the Guardian's implementation of the @anywhere service (which is like Facebook Connect: it lets people tweet from almost anywhere but without having to hand over their login details; if you want a guide on how to use it, here's Michael Brunton-Spall's, one of the Guardian developers who worked on it).
A few of the statistics (and our questions)
• Twitter has 105,779,710 registered users (our previous best guess was 45m - though this 105m, soon to be 106m, isn't active users, of course)
• 300,000 new users sign up per day (but: how many are spam?)
• Approximately 60% of them are coming from outside the US
• Twitter receives 180 million unique visitors per month (is that to twitter.com, or totally?)
• 75% of Twitter traffic comes from third-party applications
• 60% of all tweets come from third-party apps (those tow make an intriguing combination: third-party apps are used more to read than tweet?)
• Since the new Blackberry application was launched, it has accounted for 7 to 8% of new signups (encouraging for RIM)
• Twitter now has 175 employees, up from 25 one year ago
• There are 600 million search queries on Twitter per day (that's a lot of chances for Promoted Tweets)
• There are more than 100,000 Twitter applications
• Twitter gets 3 billion requests a day through its API
• 37% of active Twitter users use their phone to tweet (that's a lot - and shows how Twitter has escaped from the web)
More will come, we're sure.
