I really liked Uncle from another world too, but I wouldn't list it to that question. I guess because it's more of a comedy than with a spanning story and depth or development.
Scrolling through the comments to remember some of them,
Mushoku Tensei - great - the first two seasons have exceptional world building, story telling, contrasting, and developments; not everything is great, but a lot is; for me, last two seasons fell off a bit
Grimgar - very good - very unique, great world and characters and relationship between them
Ascendance of a Bookworm - very good
The Eminence in Shadow - very good - exceptional satire
The Magical Revolution of the Reincarnated Princess and the Genius Young Lady - very good until the ending, with exceptional visuals and vibrancy
Life with an Ordinary Guy Who Reincarnated into a Total Fantasy Knockout - very good - great comedy with a gender bend/swap
/edit: Found two more from my list of good/decent non-harem isekais I replied to some no longer existing lemmy post.
Unrelated to isekai, but I saw from your site that you migrated from Wordpress to Hugo. What method did you use to do that? I have an old wordpress site that I keep running for somebody, but it isn't actively updated anymore. If I could convert that to static html and host it using something like github pages, that would be awesome. I looked into it once before, but there were a bunch of different plugins and methods, so the inertia of not doing it won out.
too much detail; leading up to the findings that follow
Looking at the git lot, it looks like it was in 2018. I don't remember, and it's not documented that thoroughly in the commit messages log. Looks like I had content pages in Joomla, and the blog in Wordpress.
I may have exported the content via a plugin, or separate tool that reads from the database, did exported from the DB myself. I certainly did some mass-fixups via text search and replace. (I can recommend VS Code for that.)
Unfortunately, I had other projects that I migrated, so I can't remember which one I did what. :)
Thanks for the info! I am just going to have to test some things and see how it goes. My wordpress site has quite a number of image galleries, so I'll probably have to do some experimenting to see how those work.
