A few days ago Tapbots had to remove its alpha release of Tweetbot for Mac to stem the influx of new users eating up its quota of users which was imposed by Twitter. It apparently also marked the end of the alpha program as on Saturday Tapbots released Tweetbot for Mac version 0.8.0, which it considers a beta.
While a lot of things were improved in this version, such as expanded keyboard navigation, there’s a catch, a rather inconvenient one. The beta version will not allow users to add accounts, so as to maintain it from growing too fast.
It’s not that Tapbots don’t want new users, it’s concerned about those who download the app and later abandon it, because these accounts will take valuable spots from those who actually want to use the app. Tweetbot will have account addition back but it won’t be until the app is in the App Store. If an account is removed from the beta version, it will not be usable on the app until then.
