I realize that I didn't put any permalinks in the front display. I mean it
works fine, as long as you keep to that very specific format. It constrains
the front page view to the 3 most recent entries. What I would do for a
"turn-key blogging platform" is make a rake-style task that
adds/edits/deletes/etc. the entries. Add and edit would open an editor with
the body text (it would also be possible to specify a file) but on save the
body text would go into a yaml file. Another command would edit the
attributes, like date. The default location would be blog/,  but other blogs
could be created and specified.
