If you've read this blog for any length of time, or any of my books, you know I'm big on people joining professional associations. They're great for networking, for keeping your skills up, and more. They're de rigeur for any professional.
So I'm going to assume that you're joining one, have joined one, or are so seized with guilt after the above paragraph you're going to join one.
Now, when you are/if you are part of a professional association, you want to make sure they know about things from the geeky side of things. They might not always know about the people who have a passion for the same subjects they do – but are coming at it from the fan/geek/otaku side.
