Great news for Twitter developers!
I just noticed in my web app iTweet that Twitter is reporting a maximum of 150 API requests per hour now! Hurray! This is great news for Twitter clients, as the API limit is a constant challenge in user interaction.
Twitter had mentioned that this was in the works, but so far I haven't heard mention of them actually launching this upgrade. I hope it is here to stay!
They have also recently fixed a long-standing bug that caused followers/following methods to report incorrect data. Along with this fix came some new API methods for managing follow relationships - I will be updating iTweet with a new follow/unfollow UI just as soon as I can get to it!
There are some really great improvements coming soon to iTweet.net - stay tuned for much much more.
