Tweetdeck is a pretty amazing app for OCD inflicted psychotics such as myself. Tweetdeck allows the user to organize the chaotic world that is twitter, allowing the user to group certain tweeters, schedule future tweets, and many more features. The scheduled tweets feature included is one of my major selling points. One could set up a consistent flow of tweets to bring in a certain user base as set times, such as daily tweets. This is great in allowing the user to get them all out of the way immediately, and then having more time later for other projects.
The best feature by far is the ability to create groups for the people you follow. This is a fantastic way to separate the tweets from professional and personal worlds. One could have separate streams of tweets flowing in, which would allow an increased focus on certain subjects the users deems important.
Tweetdeck is a fantastic app for those of us who require everything to be neat and tidy. I strongly recommend this app to all twitter users.
