I started following this same system, and after realizing how much sense it made, and how similar this system is to typical digital data storage system design, I concluded I should always design physical storage systems using the same mindset as data storage.
The VS Code developers observed that things can pretty tangled with open-ended plugins and HTML rendering, so they cordon off plugins to separate processes, and only offer limited UI control to plugins. This helps keep things stable and fast, but I think the ability to have plugins easily create new UI in an open-ended way is the coolest feature that Electron enables in an editor.
Atom offers a lot more UI control to plugins, and in my experience, is still acceptably fast and stable.
As others have said, it’s a question of what you want to get from learning.
Haskell primarily tries to answer the question, “What are static type systems capable of, and what new relationships can we achieve between code representation and code execution?”
Clojure primarily tries to answer the question, “How can we write programs more efficiently in the (relatively) short term?”
del.icio.us/popular used to be very similar to Hacker News as a source of fresh web-scene-relevant article flow.
Between /popular, and per-tag RSS feeds, in some ways del.icio.us used to be a better Reddit than current Reddit. Tags and tag feeds were a very flexible way to monitor interest topics. What is now a network of reposts between subreddits, used to just be the addition of tags.
Saving a bookmark to your own set of bookmarks also served as an "upvote". This created a nice incentive alignment; if something was interesting, you would want to keep track of it, and add it to your collection, with the tags relevant to you!
Because del.icio.us was not explicitly designed as a "hype machine" like reddit, it turned over a lot of really original content that would have been hard to discover otherwise. It helped that the peak of del.icio.us was during the rise of blogs and self-published websites.
I went through a similar process recently, and ended up getting the Spindle: https://spindlemattress.com/. It's also an "assembly your own" latex setup, although instead of shopping for layers individually, they sell 3-layer sets. I'm pretty happy with it.
I liked that the layers stay separate - you can break the mattress down to make moving easier, and you can replace layers individually, if you ever feel the need (with a 30% discount if you buy from Spindle again inside 25 years).
