There is a known bug in the @anywhere application creation flow that results in @anywhere applications having read-only access. This results in @anywhere widgets like the TweetBox and Follow Button not working.
We just rolled out a fix to all currently registered @anywhere applications. However, those creating new applications over the weekend will need to grant their application(s) write permissions by following these steps: 1) Go to: http://twitter.com/oauth 2) Click on your application 3) On the "Application Details" page click the "Edit Application Settings" button 4) On the settings page for your application, scroll down to the item labeled "Default Access type" 5) Change the "Default Access type" to "Read & Write" We apologize for the inconvenience and will be deploying a fix for this early next week. We'll be sure to notify you all when the fix is rolled out. - The @anywhere Team -- Subscription settings: http://groups.google.com/group/twitter-development-talk/subscribe?hl=en
