Twitter has raised the number of times you can ask it for information using the API from 100 to 150 times per hour.

This means, when you're using clients like TweetDeck, Seesmic Desktop, TwitterFon etc... you'll be able to send/receive more messages, see more people's profiles, update your stream more often and generally have a larger buffer so you're never waiting for the the next hour to start unable to tweet (like we at RandomlyAccessed sometimes have to do).

However, this is quite a recent change, and we are unable to confirm at present whether this is a wholesale change of policy, or whether certain applications have been allowed access to more API calls.
