Until recently, asynchronous online discussions have been largely limited to text-based interactions. The continued development of “web 2.0” technologies, or “read/write web” tools, is changing the online interactive landscape, however. Free web services like YackPack (www.yackpack.net) and Vaestro (www.vaestro.com) permit users to engage in audio-based discussions with others using only a computer microphone and a web browser. The audio recordings are immediately stored to a server on the Internet, rather than being saved on local hard drives and then subsequently uploaded to a server. The process is amazingly easy and straightforward, providing multiple benefits for users as well as instructional possiblities for educators.
