I did an entry the other day with references to the semi-fictional aspect of a blog, and the characters who may appear in it. I deleted it (without copying it first) so I have no real memory of it, but one of the things I was thinking of when I wrote it was this wonderful site about Erik Kraft's Hyperfiction writings about a character called Peter LeRoy - and there is commentary from a fictional character called Mark Dorset, who is the webmaster, and can be emailed.

Or start at the home page, and go into the Fiction area.
