Just a quick note… if you have decided to try building a Tropo app that interacts with Twitter, perhaps based on our blog posts about how to add Twitter to a Tropo app and how to make a Tropo app react differently per channel, you may want to be aware in your testing that Twitter rejects duplicate tweets sent in a quick time period. This Twitter Support ticket has the info:

I got bit by this yesterday testing the weather app I outlined in those blog posts. As I was modifying the code, I was tweeting out the same ZIP code to test the differences:

@danweathertest 32801
@danweathertest 32801
@danweathertest 32801

and didn’t understand why the subsequent tweets just… disappeared. I was using TweetDeck and it was only when I tried tweeting from the actual Twitter web site that I saw a quick error message pop up that pointed me to that support ticket.

Obviously if you do not tweet the same exact text, you are okay. In my case, I just started using other ZIP codes… like “90210″ and “12345″. (the latter being Schenectady, NY, of all places!)
