Comments!
The blessing and curse of building your own engine for any purpose is that if you want a feature, you have to create it yourself. I've just finished one of the features I've really wanted this place to have, namely comments. Yes, you, the reader, should you ever find your way here, will now be able to give direct feedback to what I've written. Just to demonstrate, I'll be the first.
See? It's quite easy. And the boxes comments show up in are pretty. (Although they look best with either less than half a line or more than a line and a half of text.) Yay!
Later I'll make the comment page a little nicer with a quick Markdown cheat-sheet.
