Lilia Efimova, aka Mathemagenic, is doing PhD research on weblogs and the connection to personal knowledge management, and she is having fun trying to come up with a title that describes what she is trying to do: Personal knowledge productivity or Personal effectiveness in a knowledge intensive environment. The latter sounds more "formally academic."
My interest in this has focused on the "personal knowledge management" tools - how do I combine my wonderful (but sloppy) brain with the new tools out there that help me organize and find things again? Lilia appears to be going in another direction -- that of figuring out how to be both personally effective (with one's knowledge) AND able to communicate that with others. I await her next couple of years worth of reports from the field.
