Always nice to hear of people who have been blogging for a long time. I myself have been blogging (not always very seriously) for more than 29 years. First from a '~/home' directory of the University I was working at, later I moved to my own domain [1]. The first entry is from February 1995, but it also has contents from before that date.
I am still writing HTML (with some JavaScript) using a modified version of Crystal Edit, which has the ability open local files by following HTML links [2]. (So, it act like a kind of HTML source browser.) I am using a C program to check HTML and links [3], which also places all updated files in an upload directory.
