Stop #19: Other Social Networking

My feelings about most social networking are aligned with my feelings about Twitter.  I use Facebook to keep my mother up to date on myself and the family and to keep up with my old friends, but I just can hardly see the use for it in the workplace.  Sites like Classroom 2.0 make sense for teachers because they can share ideas and tactics, but the layout was very busy and hard to read.  I just don't see what these sites can offer that my RSS feed and blog cannot.
