And before anyone says it: the way to handle the problem of "but I'd have to select a million topics in the filter!" is tag composition:

I collect all my separate "programming language" tags together and create a new single "programming" tag. Now I can filter based only on that. And if it turns out that I've done a good job of curating that "list", others might simplify their life by simply assigning high trust to my single "programming" tag.

Or, just for fun, maybe someone really dislikes my curation and construes my tag from _their point of view_ as "woke programmers" and negative-trust-ranks it. This effectively mutes me and my graph for THEM (only about woke programming) while effecting me, my point of view and my graph not at all.
