Twitter will not charge organisations for commercial accounts on the microblogging service yet.
"Whatever we come up with, Twitter will remain free to use by everyone - individuals, companies, celebrities," wrote Twitter co-founder Biz Stone in a blog post on Tuesday.
Confusion sparked earlier this week around the web, as reports emerged that Twitter was identifying ways to charge for commercial accounts.
But in his blog post, Stone said Twitter had "nothing to report just yet" and had simply been "thinking out loud".
Twitter has seen a massive spike in popularity over the last year and is now ranking at number 3 in Compete's list of social networks. According to Compete's measurements, Twitter climbed 19 spots last year and has now almost 6 million unique visitors monthly that visit the site around 54 million times during this time.
However, Twitter's Stone still leaves space for speculation. Although he says the microblogging service will remain free to use by everyone, Twitter is "thinking about adding value in places where we are already seeing traction, not imposing fees on existing services." So basically, all current services will remain free, but future corporate services might not.
Twitter and other social networks like Facebook are still due to come up with a viable business model. But so far, the companies' goal is to gain an even larger user base, which probably at some point will be used as a revenue source.
Earlier this week, Stone told Marketing magazine: "We are noticing more companies using Twitter and individuals following them. We can identify ways to make this experience even more valuable and charge for commercial accounts."
Twitter is proving very popular with businesses. Dell has 80 different Twitter feeds and about 11,000 followers. The company revealed last year that its 'Twitter sale alerts' have added around $1m in revenue.
Recent research by web analyst Hitwise revealed Twitter is now more popular than Digg's social news aggregation service, while traffic to the micro-blogging service has increased tenfold over the past 12 months.
A number of celebrities use the service on a regular basis, including tech-fan Stephen Fry, who recently used the service to keep himself entertained while stuck in a lift in London's Centre Point for over 40 minutes.
