It's not the sites. I've done spoofs on my Only Rula youtube show(see only rula dating) and you'll see I make fun of both the men and women online.
The reality is the "tango" of dating is complex. The internet is just harder to get through to the core of what people want.
So until people stop being fools, and simply forward with what they want, it's not the site that sucks, it's the people!
