I’m quite happy with Jerboa on GrapheneOS, and on desktop I prefer to visit Lemmy via Tesseract.

I love homepage for this purpose. Gorgeous, good UX, easy to configure, and lots of widgets/integrations.

I currently use Tiddlywiki for all my note taking, but I’m about to switch to TriliumNext Notes.

This is well beyond my skillset (or knowledge level), but something like ArchiveBox combined with ActivityPub might be able to distribute internet archiving, each instance sharing with the fediverse what it has archived.
