Numbers can stay but with context, let me explain:
We need a way to make profiles of the reviewers, websites, blogs, magazines, etc. a system that can recognize patterns and assign tags, flags and so on. Something similar to Metacritic or Metacritic itself.
With this "profile" we could know:
-How many "10" a website/ reviewer has given and to which games in a x period of time.
-How many games a website / reviewer has reviewed in a x period of time.
-"This reviewer prefers FPS games" (Maybe an API designed to fetch information from their Gamertag)
-"This reviewer hates Action Games" (Based on the number of Action Games reviewed by the same person / website, and their scores)
You get the drill.
Now, you could be connected to this system too. Based on your personal review scores, games you play, time you spent on those games, etc. and "affinity" system could be created.
You could know if x reviewer / website has affinity with your tastes, in theory a 10 by someone with more affinity with you, means more to you too.
This is just the tip of the iceberg, a system like this could be expanded for almost everything.
(If someone look at this post and make this shit real, please at least let me know or say "thanks" for make you rich).
