He's saying that people come in looking for information, and they look through the thread titles. Then, they see one titled "Windjammer". They think, "This might have the information I'm looking for." So, they open it up, and read through all of the posts only to figure out that IT ISN'T NOT!

"I know why you're here... I know what you've been doing... why you hardly sleep, why you live alone, and why night after night, you sit by your computer. You're looking for him. I know because I was once looking for the same thing. And when he found me, he told me I wasn't really looking for him. I was looking for an answer. It's the question that drives us... It's the question that brought you here. You know the question, just as I did." - The Matrix
