A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- NEW RULE as of 5 Nov 2024, trying it out
- Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct-----

Looks like the app wasn't developed with a scalable architecture from the start, then they strapped some caching out of desperation when users started flocking, and didn't consider the invalidation parameters for private pages correctly.
It's a little bit baffling. It's not like they couldn't have predicted this server load. I know it's tricky to foresee bottlenecks in some situations but them adding caching (a very basic thing for scalability) at the last minute belies a lack of either experience, forethought, or knowledge, I am not sure which.
