Social networking is definitely going mainstream. I see in Variety that a reality show is being developed based on people meeting through social networking service MySpace. [Note: the article led me to sign up for MySpace, and I will review it soon. At first glance, very impressive.]

Reality producer Pipeline Entertainment is working with social networking Web site MySpace to develop its second reality series based on a successful dot-com.
Pipeline already produces syndie strip "Classmates," distributed by Twentieth Television and based on the Web site Classmates.com. Prexy Matthew Papish is co-creator of the syndie reality show "Blind Date."

New skein, which is being shopped to distributors and networks, will feature real-life meetings of participants on MySpace, which like the better-known Friendster connects people through common acquaintances and common interests. Depending on studio needs, show may feature more lighthearted fare for daytime or sexier content for latenight and could run daily or weekly.
