Would they begin to post ads? Or, would they just keep the pundits wondering? They begin to answer the question today as they announced they are unveiling a new advertising program. The “Promoted Tweets” are ordinary tweets that businesses and organizations want to highlight to a wider group of users. Only time will tell how this move affects the twitter success story but it does go to show you that sometimes the best things in life aren’t free.
