Online Dating, what's your experience?

Hey everyone, 
A few years ago I tried online dating and I got teased mercilessly for it. I was on Plenty of Fish for about a year and then I met my current boyfriend (who was a complete stranger from the site) and we've been together for about three years, talking about marriage. Did this happen for anyone else? I always hear "you just got lucky he wasn't a creep." How many people have had a positive experience with online dating?
