My main user page is on the English-language Wikipedia. I tend to read my talk page there far more often then my talk page here.
I also keep a blog about Wikipedia/Wikimedia/related topics at: http://original-research.blogspot.com.
I haven't been as good about updating it in the last two months as I had in the time before (I started a new job), but I'm trying to get back into the habit again. It's inactive, but when I reviewed it a few weeks ago, there was little I wouldn't agree after 12 more years of experience in the Wiki[pm]edia world.
