Do you Go On Blind Dates?

Previously, I didn't but lately I seem to be going on one after another. Last sunday I had one with this guy who I'd been communicating with but he stood me up and has never even had the desency to call and explain himself. No character there. Then tonight, I have one with a guy I met on an on-line dating sight. Still don't know if I should go meet him... It's unnerving.
