HOLY COW!  I never knew the stats about students online in these groups.  It was astonsihing to see them!  I am just getting into the social networking world…Twitter (at home since it is not regarded as important by our IT guy) and Facebook (at home).  AS I become emersed in this technology, I am seeing so much benefits to it.  I am still a bit afraid of “letting myself out there”, and see that it could be easier for the kids to do.  The noncomformist role could be a scary one to see kids involved in, but if I were a kid today, I could see myself in that role.  I was a bit of a noncomformist myself, being on the cutting edge of technology while growing up.  I think the key is education of staff, parents and students to help move us safely into the next phase of interaction!
