Personals....tried it? good experience? is it worth the try?

Just wanted to know if anyone has used Yahoo Personals or any dating website. What was your experience? good, bad, met the love of your life, met a good friend, had the worst date ever, or OMG a stalker?! =) There was someone i was interested in...well I "winked" at him but no response. then all of a sudden 6 months later he responded. Im in that mode right now just to give it a try. What ya'll think? is it worth the try? Thanks in advance!
