OK, the categories are in place; you can now see only the entries for a particular category by clicking on the appopriate title in the sidebar. Luckily, the RSS didn’t change the edit dates on the feed so nobody got a feed reader full of old posts just because I mucked around with the categories.
I think that most of the category titles are relatively self-explanatory, with one exception. I was going to call my classic KMish category “finding stuff,” since that seems to be what most of my KM posts that are not about blogging or community-ish stuff tend to be about. However, in homage to Amy Gahran’s excellent post about putting KM in human terms (found courtesy of elearningpost), I have decided to name the category (you guessed it) “Arranging Ideas.” It’s a bit broader and deeper than “Finding Stuff,” if also a bit less obvious.
