I guess I have to back up at some point and explain online dating, how we got here, what that experience has been like. I started with online dating when this was a very taboo thing. Before television adds and billboards to help make this mainstream, probably it was 2001. At that point, this was a very fringe activity, and surely my friends who I told thought I was surely going to end up being the victim of human trafficking. Which amuses me - I mean meeting random people happens all day in my regular routine: cab drivers, people on the airplane, people I meet at the grocery store...
Meeting them via online methods doesn't really change much related to safety. Actually, if anything I might argue having an online window into someone is perhaps more insightful to safety issues than meeting them via brick-and-mortar methods in many cases.
I've tried most of the major online dating sites over the years. Mostly this has been interesting when I've moved to a new area and wanted to meet more people generally - for friends or activity partners or for dating if there happened to be chemistry. Hotornot, eHarmony, Match.com, Plenty of Fish, Dating DNA, Ok Cupid. I've met some great people, had fun dates, occasionally met someone who I ended up dating, others who I just became friends with. All in all it's been extremely positive experiences. Also some fun (and crazy) stories.
One of the most interesting things to come of online dating lately is from my overall favorite online dating site: Ok Cupid. They have all kinds of interesting data on their users, and they have started publishing some very interesting metrics at their blog: blog.okcupid.com This is one of my favorite blogs to read lately. Also I get these clever emails with random facts about my preferences or compatibility. The latest installment of this is shown in this post - they've mapped my compatibility scores with the averages across US States and also other countries, taking into account my stated "must haves" and "can't stands" and also other dimensions of preference I have specified (likes dogs or education levels or whatever). Look out South Korean women... here I come! Ha, ha, ha.
