Dell today has released new numbers relating to sales generated from online social media.

The company said today that it has generated $6.5 million in sales as a direct result from being on Twitter. The company says sales from Twitter have tripped from the last report.

Dell currently has 1.469 million followers on its @delloutlet Twitter account.

With companies such as Dell generating all of this revenue, the question remains how will Twitter generate revenue with basically no business model at this time.

Twitter is expected to monetize the service by adding premium features to accounts for a small price tag. No other information is really being disclosed right now as to availability and possible other features.

Digg developer Jeff Hodson noted in a recent post, “In forth coming versions of the API, people will be able to not only read data, but also contribute data too.”
