I have the opposite problem. I feel much safer in the chat room than I do posting on the site. I can't get it out of my head that I'm more exposed here, and that anything I write is available for all to see. Whereas in the chat, I can get immediate gratification and know exactly who will see what I write. I'm also kind of a perfectionist and my mind often doesn't string sentences together properly. So if I can't say exactly what I want to say in the forums, I often just don't post at all.
