I'll take issue with the argument. I'm on the border between being GenX and GenY. I moved to a new city about a year and a half ago and brought my Twittering habit with me. Fortunately for me, my new city is very plugged in via Twitter, and local Twitter users started finding me there, and I found them. Pretty soon we started meeting up in real life -- and that included community leaders and the average gal like myself. If anything, Twitter helped me to strengthen my ties to my community in a way that I hadn't experienced before.
