I'm gonna go with No.
IMO, I don't see how online dating could work, whether you met the person on the internet, or know them IRL but just keep in touch online. For one thing, it would be far too easy for the person to lie to you, cheat on you, or completely disappear. Look at the amount of trolls we've had on here that have used pictures of other people's pets as their own, it would be far too easy to lie. Plus, it can be hard to convey emotions etc. over the 'net, I think it would be hard to have a serious relationship via a chat room or emails.
On the other hand, a lot of my friends in real life, I initially met over the 'net. I think you can meet a lot of cool, interesting peoiple online that you may not have met otherwise, and it gives you the chance to get to know them before you meet them. I've met people from the 'net before, and will continue to do so. So, I think internet friendships can work, but not dating.
JMHO
