Evaluate with the Thinkmeter

Do you have students rate books after they read them? Or maybe you want them to collect information about a variety of topics or products to determine which one is most appropriate. I just tried Thinkmeter for this purpose and I really liked it! You do need an email to use the free service, but you do not need to create a log in. (You CAN create a free log in if you'd like to save and edit all of your work.) Students can vote, rate, and provide feedback. You can also enter an amazon link for a book to instantly embed a summary and visual of the book or item. Let me know what you think!
