but it’s the one many first-time Fediverse users coming across from Twitter end up on.

That’s because it’s the only one ppl will mention as an alternative. Stop telling ppl to try mastodon, tell them to try firefish or akkoma.

Also, the jump effect is way overstated. Some users do end up moving to other software, but many more just leave because they don’t like mastodon.

It’s not OP’s fault, but voting is how we’re supposed to curate content. This post doesn’t have a title or description so it’s a bad post on lemmy and I think downvoting it is acceptable. Don’t consider votes a reflection of a user’s value or standing

Agreed. This is a lemmy bug. The OP is on mastodon (where video previews are fetched and displayed) and has no control over how its rendered over here. It’d be nice if lemmy fetched the title and description
