CoTweet has a number of nice features that make it a great choice for any business that wants to get serious about using Twitter, and the fact that it is now available for free also gives small businesses and cash-strapped startups a chance to play the game at the same level as the big brands.

As you would expect from a tool like this, you can easily invite multiple users (up to 6 in the free version), hand out assignments to members of your team (which can be accompanied by notes), and create persistent searches (for your brand name, for example). Other interesting features in CoTweet include the ability to schedule tweets, see statistics from bit.ly in a sidebar right on the site, and set up email alerts for replies and direct messages.

Thanks to keyboard shortcuts and a no-nonsense design, using CoTweet is extremely easy, and even though it is meant to be used by multiple users, it's actually also a great Web-based Twitter client in its own right.

Free For Now

For the time being, CoTweet will remain a free product, though it is not clear how long this public beta will last and what CoTweet will charge afterwards.

If you are looking for a tool that will allow your team to easily post messages to one Twitter account, then CoTweet is definitely worth a closer look.
