Twitter plans a marketing campaign starting in the next few days to educate users, individual and corporate, about ways to make money off the popular microblogging site.

Co-founder Biz Stone also told Reuters the company is not interested in acquisition talks with Google or any other company.

Documents that were posted on TechCrunch revealed that Twitter had been in discussions with Google, the largest internet search engine in the United States and a behemoth in online advertising, about some form of search tie-up.

"We have ongoing discussions with a lot of companies. One of the ways we look at Twitter, and the landscape in general, is not as a zero-sum game but how we can reduce a lot of friction between a lot of companies," Mr Stone said in an interview at the Fortune Brainstorm: TECH conference.

"In other words, we see ourselves as complementary to big social networks, to search engines, to big commercial sites," he said.

The documents included a company forecast Twitter would take in $4 million by the fourth quarter of 2009, and grow to 5,200 employees and one billion users by the end of 2013.

Mr Stone called the documents notes from meetings, out of date and not necessarily accurate.

"The key takeaway there is that we're thinking big and we're in it for the long haul," Mr Stone said.

While the site has skyrocketed in usage and prominence, Mr Stone said it had yet to make any significant revenue. Mr Stone said Twitter is in it for "the long haul" which is why it is developing ways to generate revenue, creating a company culture and doing other things internally that "you just don't do if you're interested in being acquired."

Twitter - which lets users from celebrities to businesses to politicians and protesters post "tweets" of up to 140 characters - was co-founded by Biz Stone, Evan Williams and Jack Dorsey, and is backed by VCs Spark Capital and Union Square Ventures.

Mr Stone said the company will work to educate companies, including mom and pop shops, on how they can use Twitter for their business.
