Jaiku:

Jaiku is considered the main competitor to Twitter. Most features are similar to Twitter as well.

Tumblr:

It inlcudes a variety of features. Text is a staple, but also photos, quotes, links, chats, videos, and what is nice is the fact that you can select different templates for your micro blog along with being given the option for a ‘custom’ template if you want to get into the CSS of your template.

Pownce:

Pownce is one of the latest entries into this space. Besides text messaging, it allows users the ability to share links, files, and events with anyone on their contact list. It has a nice Web 2.0 design and feel to the website.

This is the Twitter of the French and German markets. Of course it is very similar to twitter in its functionality.
