Tweetbots is a web service that extends Twitter to let you control and automate Twitter using bots like: DM-tweet, feed-tweet, auto-follow and more to come. Feel free to suggest a bot. If we like your idea it might become a feature of Tweetbots.

There’s not a lot to the design. I kind of like that, it’s clean and minimal. The app does very simple stuff so why over-complicate the design? It’s simple yet it just feels complete, like all the little pieces are tweaked as much as they can be. I also like the way they’ve done the rotating logos on the right side.
