Glue is all about connections--connecting you with others. When you visit the sites you would normally visit anyway--Amazon, Barnes & Noble, GoodReads, LibraryThing, Powell's Books, etc., you'll find that glue is there and waiting for you. You can mark books as your favorites. You can even share your thoughts on the book--keeping it short and sweet! But perhaps more importantly, you can see what others think about a particular book. You'll see if any of your friends like the book. You'll also see what other people thought about it. (You might discover someone who shares your tastes in books and make a new friend...or two...or three). Glue knows that a book is a book is a book.
