I’m not sure I can see the difference between this and dev.twitter.com, other than design, at least for existing apps. Can you summarize the functional changes? It would make it easier to provide feedback.
I am, however, very intrigued by the mention of “including rate limits”. That is the bread and butter for app devs. An increase can change our entire code architecture, and a decrease can kill entire products, as we’ve seen before. Could you possibly provide details on the new rate limits? One of my major tasks is advising people on code architecture and feature feasibility based on these limits.
If you want any advice, the /followers/ids and /friends/ids limits are WAY too low as of 1.1.
