Whether you’re an avid microblogger or you’re looking for more sites to include in your online reputation management program, you might be surprised to learn that Twitter isn’t the only such platform on the Internet although it is witbout doubt the most popular and widely used of its kind. Here are three more to get your teeth into:

12 Seconds used to essentially be a Twitter application but has now attempted to branch out on its own. It’s really a micro video blogging platform and rather than providing users with 140 characters of text it encourages users to post video updates that are 12 seconds or less in length. Great for video blogging regulars that are up to a serious challenge.

Posterous is an ideal choice for those that believe micro-blogging should be made as simple as possible. Sign up using nothing more than your active email address and then you can simply email your most recent updates to the increasingly popular website. It even lets you integrate your Posterous updates into social networks like Facebook and even Twitter.

If you’re looking for a single microblogging platform that enables you to do virtually everything you can with other social networking websites FriendFeed gives you all that and more. You can add just about everything from your Facebook updates to your Tweets to your video blogs and display them all in your FriendFeed feed. The problem with this amount of information is that it may well lead to information overload for you and your followers.
