It's no secret that Twitter is holding a tight rein over third party developers with their limited number of tokens rule. We've seen clients go under because of it on both Android and Windows Phone, and it certainly was a factor in the development and release issues we've seen with Carbon that has everyone up in arms.
In case you haven't been keeping up with it all, Twitter has placed a limit on the number of users who can connect an application to their Twitter account. Folks writing new apps are allowed just 100,000 "tokens" by default, severely limiting how many users can actually use their application with Twitter. There's plenty more rules, and if you're in a position that needs to know them all be sure to visit the Twitter developers site.
There is something we can do to help, though. When you connect an application to your Twitter account, it's listed in the account settings online. From there, you can revoke it if you're not going to use the application, thus freeing the token for someone else to use. It's pretty simple to do once you know it's there, just look in the settings > apps section of your Twitter page on the web. It's a small, but important thing we can do to help the developers who make Android great. Hit the break, and see exactly how it's done.
