Twitter has 105m registered users – how many are active?

Lots of coverage and numbers coming out of Twitter’s first development conference Chrip, the big one being that Twitter has 105 million registered users, but no word on how many of those are active.

Biz Stone told the audience that Twitter has 105,779,710 registered users – but what we really want to know is how many of these active tweet and tweet more than you know three or four times if at all?

The 105 million figure is a lot more than the best guesstimates that were floating around the web that put the figure at 60 million.

Each day Twitter is signing up a whopping 300,000 new users. TheWallUK was one of them. And yes we will be tweeting. Maybe more than once.

Interestingly that equates to a mightily impressive 10m new users a month give or take, which means Twitter is on course to double in size within a year. Still Facebook and its 400 million plus users is a long way ahead on the social media track.

I’d really like to hear how many of these new sign-ups are spam and how many accounts Twitter is deleting each day?

In terms of traffic Twitter is receiving 180 million unique visitors a month. No surprise to anyone to hear that Stone said that 75% of that traffic comes from outside of Twitter.com. Great news for developers who might be feeling under threat as Twitter flexes its development muscles and begins to build more tools of its own.

Be really nice to get a break down on that. It will be interesting to see if Twitter’s acquisition of iPhone app Tweetie impacts that 75% figure.

There was good news for RIM maker Blackberry in all those figures. Since its launched its new Blackberry application (big improvement on other apps) it accounted for around 8% of new signups.

There is a lot to play for in the handheld Twitter market: 37% of active Twitter users use their phone to tweet. How many tweets do you reckon came out of Chirp via mobiles? The Twitterfall must have been streaming like a screen from the Matrix.

Twitter gets 600 million search queries a day. That’s huge and rising and it means that Twitter’s newly announced Promoted Tweets programme will have a lot of scope.

Although bizarrely (naively?) Twitter COO Dick Costolo said that Twitter’s “promoted tweets” are “not ads”? Um so tell us what are they? Answers by tweet only (please identify your sponsor when doing so). I’m sure he knows that there are some very smart people using the service. We know a duck when we see one (I’m pretty sure promoted tweets will quack).

CEO Evan Williams later told the audience that that developers are making three billion requests a day through the APIs showing how active and busy the Twitter eco community is.

Bonus fact: Twitter is no long a 140 person organisation. It has 175 staff. Apparently the character on Twitter count will increase accordingly. Would an extra 35 characters be of use (I jest, but I’m sure you got that)?
