My long-standing blog - 20+ years over on WordPress - has a huge amount of content with functioning linkage, let down only by external link-rot from the earlier days. At the very least I want to preserve it as a functioning archive, with a front and centre link to wherever my current writing ends up. In the last decade quite a few embeds are from Twitter and, with all the changes there, they are particularly prone to link-rot as people delete their own histories.
That initial preservation - hopefully as static HTML, without any dependence of external links or databases - is just one thing. I would continue with Wordpress except for a few snags:
Glitches in Dashboard, Stats, Page & Post Editing and in published Page & Post functions:
(1) loss of auto Pingbacks from old posts to new links.
(2) unpredictable behaviour between Classic and Block Editors and advanced editing Plug Ins.
(3) unpredictable behaviour losing “sessions” requiring fresh log-ins every few mins between the different functions above. Secure but time consuming and very annoying!
So, after taking a full back-up I have some housekeeping to do, updating themes and plug-ins in Wordpress and my host Dreamhost. And then investigate a static archive as insurance?
Then switch Wordpress to Wordpress or Medium or Substack?
And switch Twitter to Twitter and/or Discord and/or Mastodon?
Watch this space.
