OK, I’ll admit it, the blog post titles are often more about puns and culture references than about what’s in the text. Worse yet, if you happen to have started reading the blog in the middle of a sequence, WordPress’ structure doesn’t make it easy to find where to get back to.  Here’s my attempt at a general guide to what each post covers.  If a link is marked with a number, you’ll probably get more out of it if you start reading from number 1 of the sequence.  Unnumbered links aren’t so linear so they’re listed in chronological order mostly.

Oh, and you’ll find some titles repeated under different headings.  Not a problem, they all go to the same post.
