-And in addition to the longform variant of writing on this blog I'm adding a
-tumble log (no, not Tumblr, although I'm planning to migrate old posts from
-there).  It generates static pages (like Coleslaw), which will be okay for the
-forseeable future and can therefore be deployed absolutely everywhere.
+Yay, found time to give my tumble log a little theme upgrade.  And while I'm
+doing that, I thought I could write down some thoughts on the current design.
+I might even update it later.
+
+In contrast to this Coleslaw blog I've made a small static renderer to
+HTML/ATOM for the tumble log, so the interface is mostly console vim to text
+file with S-expressions.  Since at the moment there is only a single file I
+might just show the syntax for that one:
+
+    ;; -*- mode: lisp; coding: utf-8-unix; -*-

+Clearly this would be viable to store in a DBMS as well, but this is good
+enough as they say.  Featuring `PURI`, a few other syntax extensions, (my fork
+of) `CL-WHO` (for XML extensions) and `CL-MARKDOWN` for text rendering.  The
+Markdown rendering could use a few fixes for edge cases, but in general it
+works pretty well and fast.  Tags are also written to separate files (both HTML
+and ATOM), so readers could actually restrict themselves to a few subsets, even
+though it's not a by any stretch a full-fledged query system.
+
+Still, by rendering to static files a lot of problems go away and the whole
+site can be served very efficiently via a small web server (I'm leaving
+Hunchentoot/teepeedee2 for more involved projects).
