What SHMUP said.
At the moment it doesn't do anything... but in the future if you "track" a game I believe it sends you updates about sales/news for it.
So if you tracked Halo ODST for instance, any news articles that appear that include the game (presumably it will use the "related games" feature from news articles) will be sent to you, possibly as a link or something, or in an automatic PM.
