This wasn't my first time meeting someone offline. The first time I ever did, it went really well, but that was years ago during myspace days.
Sites like this are a different breed. Even if everything in you says the person is amazing and absolutely nothing can go wrong with meeting up irl. Even if you (think) you know pretty much everything about the person and vice versa. Everything can blow up in your face just like that once you're face to face.
I appreciate the positive sentiment, but I still strongly disagree.
