Are students hurt by social media?

Is Twitter hurting students? According to a post by Carin Ford of Higher Ed Morning.

Dr. Tracy Alloway of Scotland’s University of Stirling, says her study shows using Facebook stretches our “working memory” (our short-term or recent memory), while Twitter, YouTube and text messages tend to weaken it.

The study Ford cited focused on younger students. Ford went on to say, "prospective college students are increasingly using Facebook for more than just social interaction. According to a new Kaplan Test Prep and Admissions study, more than 70% of college admissions officials have received “friend requests” from students using Facebook and MySpace."

This brings up other questions, what are the ethical considerations of teachers friending students on social media sites, like Facebook? Since these sites may not be as accessible as university provided media outlets; are faculty members putting disabled students at a competitive disadvantage by "friending" non-disabled students on social media sites?
