How is this different than meeting someone at the bar?

Stupider(tm). People are dumb about computers and the interwebs.

And in the way of the internet Ashley increased volume of adulterers. So, at least two differences to your local bar.

There isn't any pretense of "wanting to get to know someone" or "looking for a serious relationship leading to marriage" or "not being that kind of a girl", or even "who pays for drinks or dinner." It's just frankly about hooking up for sex, and a foregone understanding that it's for married people who want to commit adultery.
