Eurgh. Either people are giving some purposefully bad advice, or we have a load of people who are destined to be alone.
Just relax. You'll find that most people are essentially the same as their online personas (though generally more polite IRL). With meeting people IRL from the net, you've given yourself a headstart because you already know what they are like. There will of course be some awkwardness when you first meet, but just be lighthearted about it. Having a giggle will make it all a lot easier.
In terms of conversation, start off with topics you know you are both interested in (god bless Facebook). Don't assume that women just want to be listened to, and make her do all of the work. A good golden rule if you're worried about conversation is try to ask as many questions as you give answers. That way neither of you will feel uncomfortable when conversation is dominated by one or the other.
Don't worry about fibs you might have told- everyone overeggs a cake from time to time. Just be honest before little white lies get out of hand.
