Google looks set to introduce comments on search results
Currently, it seems that a commenting feature is enabled for soccer (football) match results for popular teams. For instance, searching for Brazil national football team will display a green-themed infobox. Details such as matches, players, and news are available to view. Clicking on the matches tab takes the visitor to a list of past and upcoming matches. Results with videos, in the cases I’ve tested, have a comments section within them.
