In the second article there is mention of some static CMSs that I don't think made it into our old thread (http://th3core.com/talk/web-development/flatfile-cms-du-jour/). Looks promising.
I open pages nowadays that ScriftSafe blocks as many as 40 outside page elements. On brand-name sites, I almost never see less than 20. I can usually get the page running by turning on 2-4 of those. It's ridiculous.
