I added a page-based section to this blog, to serve as a wiki-like extension. Where blogs are a stream of content, I find I have need of a more static part of the site, with content that can serve as reference, as a jump-off page to blog content, or to document things.
In the 00’s I used to have a wiki living alongside this blog, and think of ways of connecting my blog to a wiki (in 2004 I wrote a WordPress and a Movable Type plugin to let blogposts and wiki-pages synchronise). The wiki I ran was wikkawiki, which based on functionality would still be my goto choice for an open source self hosted wiki.
The issue with running a wiki exposed to the public was that it attracted loads of spam attacks, something that in practice never was outweighed by the use bona fide visitors made of the wiki to alter or add content.
In short to add wiki-style functionality to my blog, the only functionality that is really needed is that 1) I myself have a edit button on static items, 2) the ability to categorise and tag those items, and 3) keep those items outside of the blog posting stream on the front page, and outside of the RSS feed. WordPress pages fit that description, when I’m logged in, and after adding a plugin to allow categories and tags on pages. So a page based section it is, or rather, will be over time.
