Ian's blog doesn't appear to have a way to index into articles, so you have to scroll through to find the article. They are dated and ordered by date, so I'm using that to reference his blog entries (like December 19, 2004 to indicate his blog entry on epilepsy).

Ian worked at PA.net for a good bit, and given all the projects that he's working on at any given point (and completing), he's easily one of the 3 most productive people I've ever met.
