This demonstration [1] of a web-based editor [2] (link via DECAFBAD [3]) looked promising and the instructions for including it withing a webpage were easy enough that I decided to give it go.
Turns out I don't really care for it that much, as it doesn't suit my style of writing on the web. The HTML (HyperText Markup Language) it more WYSIWYG (What You See Is What (more or less) You Get) than structural, and I write structural HTML. I suppose I could modify the code (written in JavaScript) to make it more my liking, but I'm not up to slogging through 60,000 lines of JavaScript to fix a few problems for something I may end up using.
It might, however, make editing of existing entries pretty sweet, to fix typos and word choice from within the browser instead of the method I use now (which involves logging onto the webserver and editing the raw entry in an editor). I might have to try that.
