Mediabistro has reported that according to their calculations Twitter would hit the 500 million registered user’s milestone today.
This would be a phenomenal achievement for the company which has pretty much stuck to their roots and are still largely a status update platform.
Twitter is in the process of rolling out advertising solutions for small businesses and this new milestone would just highlight how prominent they have become for marketing on the web.
It would be interesting to see how accurate Mediabistro is with their estimates. Twitter is likely to make an official announcement when they actually hit this latest milestone.
