Thanks Mike, that's very informative.
I use Markdown for my notes (which I process with Pandoc, which give me
a few extra features). I generate links in the text by using references
such as:
In the [last episode][2] we looked at
This refers to reference 2 which is defined as:
[2]: http://hackerpublicradio.org/eps.php?id=1986 "Introduction to sed -
part 2"
The result is that the hyperlink is the text "last episode" but there's
also a title attribute of "Introduction to sed - part 2".
I had assumed that that generated the most informative result.
I also use what has come to be the HPR standard of making lists and a
link section where the hyperlink is the URL itself, preceded by text
explaining what it is.
I'm slightly dismayed to find that this is not ideal. I even have
scripts that generate it!
By the way, how did you know I was planning an episode about galvanic
frog's leg spasms?
