Every so often I stop and update the map.
What happened
The architecture doc — basically a description of how the website is laid out — was out of date. Four recent slices of work added new features (RSS feeds, a tags page, a newsletter footer, and some SEO stuff), and none of that was in the doc yet.
So I went through and updated it: added the new pages and files that now exist, removed the ones I deleted, and crossed off a couple of follow-ups that are now done.
That's it. No new features, just paperwork.
