One thing that's always been difficult for me is keeping track of the comments on my blogs. So,
here's a PHP / javascript hack that generates comment summary pages.
Follow that link and enter your blog details (it'll work for people hosting blogs here at Salon, on the standard Radio server - radio.weblogs.com - and on my own
Python Community Server), then click the button and you will be presented with a nice reverse-date-ordered list of comments.
Once you've run through and read all the comment pages, all the links will be purple. When somebody posts a comment, the link URL on that page will change, so the comment ID linking to the page with the new comment will turn blue.
Examples:
this blog,
Workbench,
Dave Winer (DHRB)
Enjoy!
