Wiggio has come out of its beta, all new and loaded with features to help college students with (reminds me of Yammer). It provides plenty, enabling students to create private groups, integration of streaming messages (like Twitter), calendars, text and voice messaging, sharing etc. The service is already a hit with its userbase close to fifty thousand and college students are definitely finding it more than just an online assistant to help them with academics, extra-curricular, etc.
