TweetDeck is a Twitter client that helps you keep track of everything on your timeline. It’s core feature is a multi-column view that lets you group your tweets together however you’d like. You can add friends to groups, so their tweets will always show up in a particular column. A column can also be configured for search, so you’ll see any tweets with your search term in them. I often use search when watching a prime-time TV show live, to see what other people are saying about it, or to see if anyone picks up on some subtlety that I may have missed. It can make TV watching a very interactive experience.
