Internet dating's not for everyone, especially those who are a bit ignorant of personal space or dating in the first place; there's simple nuances that an inexperienced person probably won't learn to not do their first time around that probably wouldn't happen if they met the person face-to-face first. If we're talking about long-distance dating through the internet, then it's pretty agreeable that it's had about the same success rate as normal dating has; though, this was probably less true when it first started up.
