Mike and Jessie introduce Innertoob, an asynchronous learning tool for communication and sharing information. They highlight that it allows users to listen, reflect on introductions to topics, and participate in communication through reading, listening, viewing and typing. The tool has been used at education conferences and for company meetings. Key features they like are its easy navigation, ability to edit and reply to posts, embed content in other webpages, and use asynchronous annotation and collaboration. They suggest potential improvements like making the interface more appealing through better color and ensuring audio players are compatible with Flash. Resources include a beginner tutorial and FAQ.
