At a time when other social networking sites like Facebook (NASDAQ: FB ) are struggling to figure out their place in the foreseeable future, Twitter (NYSE: TWTR ) is enjoying the fact that it has just recently figured out what it is and how to sell itself. Revenue is on pace to improve nearly 23% this year, driving per-share profits from last year's 44 cents to 80 cents. The pros are calling for sales growth of nearly 14% next year, though, which should drive the bottom line up to 89 cents per share of TWTR stock.
