I found this article on Techdirt interesting. Why? Well, I met my spouse online.
I dated online for about 4 years before finding someone eminently worthwhile. Well, I may have met a couple others in that time who could have been worthwhile, but since I had only me to satisfy during the selection process, we'll have to go with the possibility I could have made a mistake or two. I'm certain a few women who ran for the hills after a few conversations and/or dates made similar mistakes.
I have sometimes bragged (or complained, you choose) that at one point I went on 7 consecutive first dates. You could look at that as a low point in the cycle, but I did learn some valuable things in the process. One thing is not to give up and settle for less. Another thing is that there are a lot of "unusual" people out there, and you are bound to run into a few of them from time to time.
To more or less reiterate parts from the above-cited article, online dating is not a substitute for real dating. It's simply a way to meet people. It's also a somewhat less risky way to get acquainted, since you can talk at length with someone before actually deciding to meet them in person. If during your online "conversations" (chat, email exchange, etc.) you decide it isn't going to go anywhere--for whatever reason--you can simply break it off quickly and cleanly and move on to something else.
One danger I would mention is the unfortunate tendency for two lonely people to let an initial good impression get carried away. Before meeting someone for the first time, you should not become infatuated with them. If you do, it won't be very much fun when they turn out to be ... er, less than you had hoped. Yes, even knowing this (and I did) I had this happen a couple of times. I don't lead with my heart, but I do have one (heart, that is). I think this happened a few times with women I met. One I actually liked a lot, but she evidently felt my reality wasn't up to her standards. Yeah, don't let your imagination get carried away. You'll be disappointed.
I don't see online video speed dating as a problem. In fact, I can imagine it sorta ... speeds up the process. Duh. In the "good old days" of online dating, you actually had to use a chat client or maybe the--gasp!--telephone to get better acquainted. It wasn't visual, which could be the reason we allow our imaginations to get out. I'd think getting acquainted with both audio and video would much more quickly weed out the undesirables.
Having the other person show you things you don't want to see is only a small, temporary issue, since if they violate the dating service's terms of service you can quite easily have them banned. In any event, as the article points out, the whole purpose of online dating is to find a long-term partner, so if seeing some guy's naughty bits isn't your idea of appropriate behavior, then at least you know this guy isn't for you. Conversely, if you meet a woman and she proceeds to act in a way non-inducive to her long-term success with you, well, at least you know. And more quickly, as well.
I am surprised that some seem to think that online dating eliminates the need for more conventional methods. I find an analogy to this in how some online retailers have seemed to think that it (being online, that is) eliminates the need to have a sound business plan and sound business practices. At some point, online or not, you have to deliver the goods. Since finding a partner/mate is a person-to-person endeavor, you really do need to get into that squishy aspect at some point. And quite frankly, sooner rather than later. Meeting the person you are considering for a relationship is sound "business" practice. In fact, you need to invest oodles and oodles of time in that person before things can get around to working out.
No surprise, there.
I chose to meet women online because I had little opportunity to meet them via other avenues. Sure, I could have gone to bars, but I deemed the probability of meeting my "one and only" to be so very much less likely. People go to bars primarily for one thing. While that part may be nice, it's not the most important thing. Unless I got lucky and met someone nice at work, if I wanted to find someone, it was probably going to be outside of work. The Spockian logic was impeccable--online was a very good way to find women.
Since I am now married and since we met online, I can definitely say that it can work. But like anything else, it's not guaranteed to work. It just gets you in the door. What happens after that is purely up to you.
