In case it helps my fellow #mastoadmin crowd... infosec.exchange had a pervasive problem where thumbnails/previews for images and links would not show, either for things posted locally or for posts from other instances in the home or federated timelines.

@nova pointed me to the S3_FORCE_SINGLE_REQUEST=true setting in .env.production (i.e., I needed it and didn't have it). That was half the fix. The other issue is that I am (or was) using two servers dedicated to running sidekiq jobs. It was only when I made that setting change AND I shut down sidekiq on the second server that this started working correctly. I still do not know why the second sidekiq server caused that, but here we are.

While following a lot of people can populate your Home feed significantly, sometimes people (like me) end up boosting a lot and that can unexpectedly hinder your own experience.

So if you like someone's specific posts and don't want to follow their boosts, you can go to their profile under the [...] button, and select the "Hide boosts from account" button.

There is no algorithm on Mastodon. You have ownership and control over every filtering decision instead of some robot.
