Twitter is planning to charge brands for using the micro-blogging website.

There has been much debate about how the micro-blogging channel would be able to translate its business model into measurable ROI.

A report from Brand Republic reveals that Twittter co-founder, Biz Stone, says “We are noticing more companies using the site and individuals following them. We can identify ways to make this experience even more valuable and charge for commercial accounts.”

Stone also indicates that it could also create revenue-generating features to tap into the way brands use Twitter as a hybrid marketing and customer-service tool, but would not be drawn on the level of charges. Stone insisted Twitter would not charge individual users.
