extreme correlation between social groups and behaviors

A colleague mentioned the other day when we were talking about adopting google calendar, "doesn't everybody use gmail" which reminded me that yeah, pretty much everyone I know uses gmail, which is interesting because overall, gmail only accounts for 7% of email accounts, and even amongst online e-mail services, gmail is third behind hotmail, and yahoo mail (4th if you count apple mail which has 11%).

The example I use in class is NASCAR. Since no one in the classes I teach watch NASCAR even though by some measures, NASCAR has the highest attendance of any sport in the US.
