One aspect I think Lemmy lacks is the ability for some contained discussion. To much leads to feed back loops but not enough discourages niche communities.
This is something Reddit’s scale does well. Reddit communities will have most of their posts never make it to the 5th page of All. There will still be break out posts but most likely the only people reading your post are those in your community.
With the current size of most niche lemmy communities you are posting to thise in your community as much as you’re posting to who ever is viewing All by new.

Not a mechanic but even if it is technically too old you maybe be fine if you keep it and in the event you get a flat simply replace the flat with a new tire, after getting to a tire shop on the spare.
