Yet another good idea from firinel: here's a tool which takes a snapshot of your LJ "friends of" list the first day you use it, and then on every subsequent day it shows you how it's changed. So you get a list of who's friended and unfriended you recently.
If you'd like to link to joule yourself, here's the HTML to add to your journal or your userinfo page:
<form method="get" action="http://marnanel.org/joule"><tabl
Obviously, you need to keep coming back to this over a few days to make it useful. Here's an example of what it looks like when it's been run over several days.
Feedback, ideas, criticism, questions, whatever-- it's all welcome: feel free to comment to this post. Thanks to firinel whose idea it was, pacx who thought of the title of this post, and everyone who's found it useful so far :)
