For the time being, I am going to use Obsidian for keeping notes about the photography. I like the cleaner look of it over TiddlyWiki. And running it via Linux on my Chromebook is a bit easier than using Tiddly Desktop. I have had some minor syncing issues but I don’t think that’s a significant problem, I think I’ve ironed those out.
The major issue for me will be NOT to get sidetracked into fiddling with the information system instead of dealing with the information itself.
