Wouter Groenveld opined on his personal blog (I recommend adding it to your feed collection) that blogs should have About pages. I submit for the record that I wholeheartedly agree (albeit my About pages have a different emphasis).
Blogs Should Have About Pages
The site stats tell me that my about page at /about is consistently one of the most visited pages on this website. That confirms what everyone already knows: people are very curious, sometimes even nosy.
