Each month, we look at Twitter’s growth in terms of new user registrations, number of tweets, and tweets per user registration. This info is provided by Matthew Daines, the lead developer of Twellow, our Twitter app, which serves as the Yellow Pages for Twitter.

Last month at Chirp, Twitter’s Developer Conference, the company announced that it was up to 105,779,710 registered users, confirming Twellow Developer Matthew Daines’ estimate that they had surpassed 100 million users.

Update: Well Daines was right in that Twitter has surpassed 100 million users. At the company’s developer conference today, Twitter announced that it has 105,779,710 registered users, as well as that it gets about 300,000 new users a day, receives 180 million unique visitors a month, and 75% of traffic comes from outside of the Twitter website.

Each month, we look at Twitter’s growth based on total tweets and new user registrations. This data is supplied by Matthew Daines, the lead developer for our own Twitter app Twellow.

Our Twellow team has been working hard on getting Twellow set up to use Twitter’s OAuth system, and that support is now available on Twellow.com.

"The Twellow OAuth upgrade is a major improvement for Twellow users," Twellow’s Lead Developer Matthew Daines says. "Not only is it much more secure, but it also increases the amount of interaction users can have with the Twitter universe from Twellow."

Every month, WebProNews has been looking at Twitter’s growth in terms of new user registration and number of Tweets. In January, we looked at December’s numbers which showed an increase in tweeting frequency, as Twitter surpassed a billion tweets in a month.

In January, total tweets sent were the largest on record. However, they increased at 6.34% over December, which is the second lowest increase for the last twelve months. Only August saw a lower rate at -6.2%.

Each month we’ve been looking at Twitter’s growth in terms of new user registration and number of Tweets. Last month we saw a decline in the number of new Twitterers in November continuing a trend that began in July.

In December, however, new Twitter user registrations leveled out. Number of tweets grew significantly, and the number of tweets from new users grew as well, possibly indicating that people aren’t just signing up for Twitter and not using it.

We’ve been looking at Twitter’s growth on a monthly basis, in terms of new user registrations and number of tweets. In October, new Twitterers were down, but tweets were up.

November’s numbers paint a similar picture. Matthew Daines, the lead developer of Twellow, has shared a couple of new graphs for last month.

Last month we looked at Twitter’s numbers for user registrations and total tweets for the month of September. We saw a small decline in new user registrations, but tweeting appeared to be on the rise again following the previous month in which tweeting declined.

The numbers for October follow a similar trend. The information was supplied by Matthew Daines, the lead developer of the Twitter app, Twellow.

Last month, we looked at Twitter’s numbers for user registrations and total tweets for the month of August, and found what appeared to be the first month of the year in which tweets sent by Twitter users decreased. User registrations also appeared to decline for the second time of the year.

Last month, there was a lot of hubbub about Twitter’s growth flat lining. Matthew Daines, the lead developer of our own Twitter app, Twellow, showed me a graph that he put together from the user IDs he found in the Twitter API, based on when they registered with Twitter.
