Facebook: luv it at home, ??classroom use

I think I should be a p.r. person for the Facebook company.  I love the online social networking!  It is a wonderful option for the full time working parent of 3 children who rarely wanders out of the 3 mile radius from her house besides to go to work.  

Facebook allows me to "keep in touch" with friends by checking on their online pictures and reading updates.  It allows me to feel like I am keeping up with people who I am only able to see in person and/or talk "live" to/with a couple times a year.  

In addition to this it is a time saver.  I can check in with people without having to commit lots of time to socializing.  I can  check in with them on my schedule, usually late at night, and not worry about the hour.

I am considering using facebook for a class project.  I would begin a different facebook page that I would use just for school and with another email address.  has anyone tried this for a class project, ongoing discussions with easy photo access, etc??
