I’ve made a few tweaks to Twitterator over the last couple days, the most significant of which is a measure of compatibility with DabbleDB. If you create a basic DabbleDB database with a single column of twitter usernames, you can specify the URL to the .txt or .csv versions of your database and Twitterator will add them to your list of Twitter friends.
This new feature should really help if you want to provide an easy way for a bunch of people to subscribe to a set of twitter users all at once. You could maintain, for example, a list of K-12 science teacher twitter users. Make as many groups as you want and simply provide the URLs in a blog post, on a wiki page, or in a Google Docs document.
Leave a comment if there’s another feature you’d like. I’ll see what I can do to put it in. Please let me know if you find a bug.
