I used "tags" inconsistently in the beginning, but have recently come to realise that the "tag cloud" in the left margin is actually a good way to pull out a selection of blog entries on one specific topic. Hence I have made an effort to include relevant tags more systematically, and have also gone back to the old entries (back to May so far) to provide a meaningful archive retrieval system.

Also fun to watch how certain (predictable) keywords grow larger in the tag cloud ...

enjoy !
