This is just a bit of an extension of the "is technology making us unhappy" thread. S31 made a comment that he'd be surprised if most people on here use more than two or three sites regularly which was amazing to me and i'd be interested to see how true it is.
So basically ignore any sites that you only visit because of work/paypal/online banking and things along those lines. Just think hard about the sites you visit at least once a week on average.
I've made the poll anonymous because you get better answers.
