Micro-blogging site Twitter is interested in making more acquisitions as it continues to grow in popularity, co-founder Biz Stone said Tuesday.
"That is something we are definitely interested in," Stone told a news conference in Tel Aviv. "We made an acquisition last year that turned out to be an outstandingly good decision." He was referring to search engine Summize, which it bought in 2008.
Stone said there was nothing specific on the horizon.
He also said Twitter will "start making money" in 2010 as it unveils a plan early next year on how it will produce revenue through advertising. He declined to give details but said advertising will be "nontraditional."
