Most people never heard of microblogging. Some heard about Dodgeball, Twitter, and Pownce, and maybe even Jaiku. Major social networks such as Facebook and Bebo have been trying to catch up with the growing popularity of micro-blogging services, adding their own flavor to the mix. But in fact, there are over 20 sites either dedicated to micro-blogging or have significant support for the format. This is not aimed to be an authoritative list of the current state of things, but it is a pretty impressive list of sites.

Few are not yet open to the public – Hueniverse’s own Nouncer being one of them. This is a lot of activity in a very short period of time, considering most made their debut in the past few months. It is well worth checking out the different flavors and implementations. As you can see, there is a lot of creativity even within the somewhat narrow space of micro-blogging. If the list is incomplete, please let us know in the comments.
