Asynchronous Communication

One of the most common tools for asynchronous communication would most certainly have to be facebook (facebook.com). Known as a social networking medium, facebook enables people to keep in touch with others by writing notes, uploading photos, joining groups etc... I think it has uses in education as well. Many colleges have facebook pages, and certainly it is a useful venue for posting meeting and course information. Another tool is tumbler (tumbler.com). This is similar to facebook in that it is a social networking tool, but perhaps has stronger privacy controls. I've played about with this a little, but I haven't had the time to really invest in this tool yet. Google also has a social networking tool, and their aim is to displace facebook. It remains to be seen as to whether this will happen.
