As I've said before, Twitter is a terrific real-time intelligence engine. Now that there's an official Twitter Android app, there are also a couple Twitter widgets (large and small) for scanning your Twitter stream. You can even configure the Twitter widget to display "Mentions" so that you can quickly see who's talking to you (or about you) and respond.
If you'd prefer to view this as a list instead of a photo gallery, then see the companion blog post.
