To those that have asked, I'm still alive.
I had to restore the blog database from a backup and so I lost a few posts, including the index for the various recursion schemes entries. Fortunately, before that happened I had replicated the catamorphism post as a knol.
Should I find myself with a copious glut of free time, I shall happily re-scribe and finish the rest, but I've been very busy.

Some pages are still in the google cache, like:
http://64.233.183.104/search?q=cache:tdL6Rp58zRAJ:comonad.com/reader/2008/recursion-schemes/+comonad+reader+catamorphism&hl=en&ct=clnk&cd=2
Ah, nice. I’ll see if I can use that to recover the content.
Between the google cache that Sjoerd pointed out and Jeff Cutsinger having just loaded the content into his google reader, it looks like I should be able to recover it all.
