Movable Type didn’t just kill off blog customization.
It (and its competitors) actively killed other forms of web production.
Non-diarists — those folks with the old school librarian-style homepages — wanted those super-cool sidebar calendars just like the bloggers did. They were lured by the siren of easy use. So despite the fact that they weren’t writing daily diaries, they invested time and effort into migrating to this new platform.
They soon learned the chronostream was a decent servant, but a terrible master.
The potato gun girl and gerbil genetics guy found they didn’t want to write updates. It didn’t make sense. Their sites should have remained a table of contents, a reference tool, an odd and slightly musty personal library… the new “posts” format simply didn’t work for what they wanted to do. It felt demanding, and oppressive.
