As Steve already did, I'm eating my own dog food, too...
So this blog now is running on Subtext 1.9.4. How can you be sure I'm not kidding you?
Just have a look at the header section of this page: it now includes a new html meta tag:
<meta name="Generator" content="Subtext Version 220.127.116.11" />
So, please, if you can, poke around, and eventually report bugs in the usual way: submitting them to sourceforge.
