Writefreely is nice looking microblog system with Fediverse integration which main purpose is to attract you to host your microblog on Write.as. You can selfhost it though and I did. And experienced difficulties you do not expect from commercial grade software.
Like a problem with not existing tables in the SQLite database. Annoying but after finding some solution (on internet not in the Writefreely documentation) it worked well. Until the next upgrade. Upgrading the db ended in an error and the upgrade got stuck. Restoring the db and trying upgrading again in a clean environment, no deal.
And that made me think. Do I want to repair a simple microblog system with every change? Do I need a web environment to write my markdown posts? Do I need close Fediverse integration. All answers are No!
So installed Hugo (links in the footer) which is somewhat more work to setup but with virtually no maintenance because it generates a static website. Old files are overwritten and everything else remains the same. Recommended.
On the other hand if you just want to microblog without selfhosting Write.as is a good option.
