but I am finding it takes so long to get to know someone and the person you finally meet can turn out nothing like you expected. Currently I've been chatting to someone for 6 months - "speed dating" in slow motion!
I've just signed on also to an online site.
There was already some great advice, and I would recommend meeting the person that you have an interest in right away. Online service is a way to meet people you might not otherwise meet - but you need to get to know them in person. I'd say after 2 or 3 short conversations, suggest a time and place to meet for coffee or a beer. After all you want to get to know a "person" not an online "persona".
BTW, there are quality people online. Good looking, fun, professionals. Have fun!
