As part of a major update to the Steam Update, Valve will be announcing 4 new updates to the community over the next 4 days.
The first was announced today and will make it easier for the Steam community to discuss their favorite games, created screenshots, videos and Steam Workshop items.
The community would then be able to rate games and combine them with related news, discussions and comments in one location.
