I peruse the sites, but I can never bring myself to pay for any of them, so things never progress.
plentyoffish is free, but I never found anyone I was really interested in on there.
I am willing to admit that my attitude sucks! Online dating doesn't feel like anything but a chore to me. I resort to it when things IRL get to be desert-like in the man department. Then things pick up IRL and I drop online like the bad habit that it is [for me anyway].
