GetGlue is the latest social network for media buffs of all kinds. Music lovers, film geeks, reality-show gurus, video-gamers and bookworms can all share their latest interests, along with impressions of those interests, with other 'Glue users. And you can quickly view profiles of other like-minded users for media recommendations. GetGlue also employs a unique "ranking system," based on users' check-ins in different categories, to determine a person's sway in an area. And you get digital "stickers" as rewards for certain types of check-ins, which can be redeemed for real stickers that can be used to, well, stick stuff.
