I now have notes about the most recent WIST updates in the Elseblog section of the sidebar. I'm usually getting 2-5 quotes in there a day (and updating several others as I go), so it's worthwhile tracking it (and being reminded, myself, of it).
Rather than have links to the individual quotes, I'm just linking to the front page. I'm showing the links with the author names (for the sake of space), but the first few words of the quotes are in the alt/title text if you hover over each link. Feedback welcome.
I'm hoping this will drive a little more traffic over that way. Remember that if you like what you see there, WIST has an RSS feed, a Feedburner-enabled e-mail feed, etc.
