Something like Mastodon is likely 90% reads, or even more. How often is the OP editing their post? When they post, cache it. Kind of like what I did by including it in my original post. Caching is a hard problem because sometimes invalidation results in serious consequences, therefore knowing when to invalidate becomes potentially intractable. In this case there would be few, if any.
