I have had 3 craigslist encounters.
One was a black girl, super cute, short and curvy with a dynamite booty. We met in a park and talked for a bit, made out a bit, and then the next day I went to her apartment and we had some really bueno sex. Over the next 6 months we hooked up another 5 or 6 times until she got back together with her ex. We've met up for drinks a couple times and have a bueno time, we have a similar sense of humor. A friend of mine bought some jewellery from her at a craft show once - I recognized the piece she bought from having seen it at the girl's house when she was showing me the jewellery she makes and asked my friend if she had bought it from a short black girl with pink hair and she said yes. I didn't go into how I knew, just that I had a friend who looked like that who makes jewellery.
Second experience was kind of seedy by comparison. This woman in her 30s posted an ad saying she wanted to fulfill her fantasy of sucking a random stranger's d at her work. It sounded fake but I responded anyway. She worked at a local theater and had to last-minute cancel because her boss showed up but she emailed me again when he left and I walked downtown to see her. She was kind of fat and really tall but had a pretty face. I was mostly just turned on by the scenario, I wasn't too concerned with her looks (I would have bailed had she been full-on ugly). We went into the back of the theater, she was really nervous, kept saying "so, how do we do this? Do we just go for it?" and laughing nervously. Eventually, yeah, we just went for it, she sucked me off, I came in her mouth, she reiterated that if we ever saw each other on the street there was to be no acknowledgement, and then I left. I've since been to a play at that theater and I don't think she works there any more... or she's only there during the afternoon or something, who knows. But I haven't seen her since.
Third was this tiny girl from Hong Kong who was super busy with school and just wanted to bang once or twice a week to decompress but didn't want to sleep with any of her male acquaintances, so she posted an ad on CL. We slept together 3 or 4 times a month for like 4 months and then gradually less and less frequently until things fizzled out. I was kind of upset that it ended because she had a very pretty vagina, was super tight, submissive, gave head with much gusto, and, outside of the sex, had a very sweet disposition.
Craigslist has been bueno to me. I give it a 9/10. Oddly, despite my bueno fortune with Craigslist (well, not really, since I've probably responded to like 50-100 ads and only had 3 actual meetups), I have never tried any other online dating. Maybe I should.
