Twitter is reinventing itself, rolling out the changes over the next few weeks, so don't be surprised to see some changes the next time you log in (or the time after that...). My favorite new feature is the "miniprofile," which will allow users to see the profile of other users without having to go to the person's profile (which has been quite cumbersome, especially during high-traffic times).
There are also some new related-content and media features.
Here's a demonstration, and some additional information (also, click HERE).
