I along with other have noticed a definite bias towards certain teams. NY, Boston etc.
Over the next month, beginning today I plan to log what the main story is on ESPN's baseball page to see if this bias really exists or if it is perceived. The criteria is simple; the main story must be directly about or mention one of the following teams: Yankees, Red Sox, Mets, Cubs, Giants and Cardinals.
If a bias exists, we'll see the trend.
