Twitter Promoted tweets and Retweets

I saw this comming, I know twitter will find a way to dig in to the ads income generation. And they sure did today twitter released a plan to take on promoted tweets, many big name company like google, yahoo, starbucks, Investingport.com, financial company, stock market, facebook, mainly all companies with urge for exposure will be willing to test drive this new marketing plan. Hope the result will pay off as expected, twitter has been home for all spammers until after twitter cracked down on it. hope not negative dip resurface, so advertisers can get thier money's worth.
