I've been around for 6+ years. I make a point of reading the newsletter every day, looking at the articles if they sound interesting and always reading the editorials. The site is my homepage at work and my first port of call whenever I have an issue as pretty much every time I'm stuck someone else has had the problem first and it's already been solved by someone.

Personally, I don't think I'd have the time to use any podcasts etc, but there's no harm in adding other strings to your bow. However, please don't compromise what is already a great resource.
