Instead of pocket I just have a personal discord server where I organize all the neat links that I find online, I write a short intro or header and some keywords

Far easier to search and more instantly readable than pocket is

I use raindrop.io for long-term "bookmarks", the saved feature from Feedly for mid-term, and plain text file(s) for short term/project-specific stuff

One fallback I've considered in all seriousness is simply an email address to which I submit articles, and access through a full-featured email tool such as mutt.

The main challenge there is that it's difficult to reorganise information once it's captured, but search tools, the ability to reply to threads, and the automatic capture of basic metadata (sender, subject, date) are useful.

Mutt specifically has a highly robust threading algorithm. I'm not sure what happens if this becomes rentrant, that is, a given child node might have multiple parents from different threads. Mutt as given presumes that any given parent reference (indicated through headers) is either parent to, or a child of, other referenced emails. I'm picturing a web rather than a tree.

Email is also extensible with regard to headers, and with mutt it's trivial to write hooks and tools to work with those.

And once email is stored in a standard format (say, maildir), there are other tools such as mh which can operate on the corpus at the shell level.
