I like the blog idea. I see yours is still pretty new. Any idea how many people are reading it? I hope you post parts of it here, whenever you feel so inclined. The main advantage of a forum over a blog is you can get feedback... of course, you're not always the main character in a forum setting
I find it often helps me think through specific situations when I write about them. One friend and I have probably traded 1000+ Hand Histories in 2004 alone... Oh, who am I kidding - it's probably closer to 5000! I've learned a LOT by doing this. A lot more than I would have thought anyway... I suspect you can get the same from writing your blog (sans the feedback, of course).
