Felix Wang had a great idea to let users post their used textbooks on their profile. As of now there are only 37 people that have added the application, but I could see this as being highly useful. The only question is would people prefer using a designated textbook application or will they go ahead and post their book for sale in the classifieds? For the time being this application is just an extension of ISellMyTextbook.com but eventually it may grow to have added features. A successful textbook application will allow users to automatically swap books based on the classes they are enrolled in and will also have a searchable database. Not quite sure why this hasn’t been added already. This may simply be another case of having a lack of features prior to launch. If you have an ISellMyTextbook.com account already, then go add the application. Otherwise, you may want to hold out until the next textbook offering.
