If social media existed when I was a teenager, of course I would have used it -- and not because it's "addictive" but because I was desperately lonely and fending off family abuse, societal hatred, indifferent peers, and being broke. You mean I could talk to people who might give a shit about me? Sold!
I used IRC and ICQ for the same reasons in college and you know what? It made me feel better having people who weren't threatening to kill me on a regular basis.
