For the past months I have been thinking about this on and off. And I decided to use a YAML block to specify meta data, just like pandoc uses. For example:
--- tags: [tumblelog] ... ## Tags are coming to tumblelog
So, last Saturday I started tagging Plurrrr's articles. It took me 3
days, several hours each day, to do most of the 1600+ articles. Today
I did the last few and some refinements. Next is adding the actual
tumblelog as currently my version only skips tags.
