Hierarchical Structures in PostgreSQL
I'm actually using materialized views and CTE with PhotoStructure (where hierarchies are arguably the cornerstone of the product).
It's pretty funny that I landed on this implementation, given that I spent a couple years building https://github.com/ClosureTree/closure_tree (one of the most popular acts-as-hierarchy ActiveRecord gems), as it (unsurprisingly) uses closure trees.
When CTE isn't available, closure trees are nice, but boy howdy, does that closure tree table get gigantic with deeper graphs.
If CTE is available, closure trees don't even come close in performance and simplicity.
(Hint: materialized paths should use a unique separator: ASCII 0x1F is applicable: https://en.wikipedia.org/wiki/C0_and_C1_control_codes#Field_...)

Trust-Based Moderation Systems
Slightly off topic:
I am trying to innovate on moderation systems and I run/code a whitelist moderated forum [0]. You can only see posts and comments from users that you follow. It's a very simple system and there really aren't any gaming vectors. One implication is that if a new user signs up and posts, no one will see it unless they follow. I've actually never used any typical censorship moderation.

For moderation, a user whitelist sits in front of the typical content blacklist, which introduces some interesting properties.

Ask HN: Websites that works with old browsers (mid-2000's browser)?
I think my forum should work:
https://www.commentcastles.org
I can't think of anything that would be broken except for maybe the logo which is an emoji character.

You're So Vain, You Probably Think This App Is About You: On Meta and Mastodon
You may want to check out Comment Castles [0] (disclaimer, I'm the creator). There are 50k comments, but I have never moderated anything. Actually, there are no moderation or admin tools built into the project.
