There’s a great piece of software called TiddlyWiki. It builds an entire (tiddly) wiki into an HTML file. You can save a new file to disc, then open it and start adding posts. The posts get indexed and linked, just like a real wiki, but everything lives in one file.
The overall effect is like the old outlining software that used to exist before it was embraced and extended by Word.
