Tapbots, the makers of the popular Twitter client Tweetbot, has announced that the public alpha release of Tweetbot has reached the user cap for alpha users, and in turn, has been forced to disable the link to the Tweetbot download.
They explain that Twitter gives each alpha release of a 3rd party Twitter client a limit of 100,000 users (or, as Tapbots calles them, ‘tokens’) which was recently reached due to the overwhelming popularity of the app.
With the above rules being in place its easy to see why continuing the public alpha/beta would be problematic. Someone might use the app, decide they don’t like it and the token would be gone forever. That being said now would probably be a good time to help 3rd party developers out and Revoke access to any clients that you no longer use.
They go on to reassure future customers that the app will eventually be for sale.
