GetGlue is the latest social network for media buffs of all kinds. Music lovers, film geeks, reality show gurus, videogamers 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.
