I just posted a new build of The Archivist (1.0.0.24), our Twitter data mining tool from the Mix Online labs.  

I fixed a couple bugs that people have been reporting and also added some new features:

First, it now updates now every 5 minutes instead of every ten minutes -- making it less likely to miss a tweet for topics that are trending.

Second, it minimizes to the system tray.  This makes for a better experience if you are leaving it open for a long time and/or you have multiple instances of The Archivist running.

Third, I've added a new data visualization, which calculates who the most common tweeters are for a search. I used the WPF Chart controls that are now shipping in the WPF Toolkit up on Codeplex.  Here's a screenshot:

Install The Archivist today! (Requires .NET Framework 3.5 SP1.) If you've already installed The Archivist, it will ask you to update to the latest version the next time you run it.
