Late reply.. but I have met one a few times. Overall it was a good experience. Completely different from online interaction. The times we met were more honest and sincere than anything I expected.
We basically did what everyone does on dates. And in the end it turned out I was the one who was less serious and less trustworthy, the opposite of what a random outsider would expect. Life is funny like that sometimes. Could've been something great, but if you don't go in there with enough trust it will never work out. Be honest, be kind, be respectful. That is all.
