I don't know. I have seen a couple sucessful online dating situations. My aunt and her husband have been together for ten years and I don't think there has been any trouble in their marriage yet. My cousin was dating a guy off the internet and they had a healthy relationship up until her death (She had Sleep Apnea).
As for me marrying, I don't plan on it. This site definitely wouldn't be of any use for me at all. I don't even think I would date online just for the fun of it. I have heard horror stories relating to internet dating so I plan to stick as far as I can from it. I'd rather be with someone whom I can see and I have known in person with out the use of a modem and a hard drive.
If it's safe then kutos to you finding a partner (if you're ready). Good luck.
