Glue, the most recent version of AdaptiveBlue’s browser plug-in, is a type of semantic social search innovation. It connects your browsing tendencies to those of your friends, buy using your viewing of books, movies and other mediums.
Let’s say you were visiting Amazon. Glue will insert links into the pages you are viewing without ever having to leave the site. You will be able to comparison shop on other sites like Barnes & Nobel. Once you visit the site of a specific book, Glue will also show you other users who also showed interest in the book. By clicking on them you can follow their browsing habits anonymously. Users can also leave comments behind to say what they thought of the item.
The catch is that your friends must also have the Glue plug-in added to their browser in order for you to see their interests. Glue only keeps track of the 20 most recent items you visited, so your list is not infinite. But since it intelligently can determine items you like and dislike it can also provide recommendations.
