 
I think it would be good to be able to hide game-listings that you have no interest in upon review.  For example, there are games that are run in languages I do not speak.  I would hide them to declutter the listings.  Similarly, there are campaigns where there would be clear problems between the GM and my play styles.  I could hide those so that I don't keep looking at them because I forget what the campaign posting says.  Anyway, it would make looking for games easier in my opinion.
