Posterous is a stylish miroblogging service that has gained attention for its ease of use, especially the simplicity in it as a publishing tool. We corresponded with the company today and were told that it will launch a "Posterous for Business," service.

The news follows an update to Posterous that allows multiple users to create group blogs that allow users to post to a group page on Facebook, Twitter and other social networks. A company logo may be placed in the Posterous blog with a description. That's a big deal. Facebook group pages are becoming important for business users. It can be a bit clumsy trying to update to group pages from outside Facebook.
This is an important development for the microbogging service, pointing to its entrance into the business market.

Xobni launched in January of 2008. The company billed itself as a social network for your inbox. Cool service. Today, Xobni places a good bit of its attention on the enterprise market.

Xobni offers a service that allows administrators to provide Xobni for employees. It can be customized and has features to make it regulatory compliant. Control features are built into the service. In November, the company announced its integration with Salesforce.com. Xobni's future looks more and more like an enterprise play.

No Going Back

There is no looking back once Web 2.0 companies switch to a business focus. The business market is so entirely different than the consumer world. Free services can remain intact but once the move happens, it's rare to find a small company that can manage to dive deep into the enterprise while maintaining its focus on the Web 2.0 world. Some have been able to do it. Wordpress is an example of a company that has had success with both consumers and the enterprise. Perhaps that will be the case with Posterous, too.
