I’m an old age redditor, and that was may reddiquette, “don’t downvote just because you don’t like the topic, maybe other people find it interesting”.

Mostly I don’t downvote at all, only on some rude or spam posts.

Reddit just become something where everyone downvote everything for no reason, even if just say “OK” ou “that’s cool”!
On Lemmy (ate least for now), not so much or I don’t see it.

If you see a post “orange is the best color”, don’t downvote just because you don’t like orange, leave a comment and express your opinion instead

PS: There’s an old Reddiquette song, the same can be applied to fediverse

Setup some RSS bots to auto-post news on your instance.

Instead of using and app for each service, you can use their page as webapp, with something like Native Alpha or web browser.

Fedilab supports multiple networks, don’t take much to run it.

There are some pros and cons of using native apps or web apps.
Native apps can have some features that webapps don’t, like direct/quick share, notifications…

Web apps you only need a web browser that’s already included, don’t take more space, use less battery for background process, and less permissions.

you should do a update and posted on Lemmy (*cof* and Reddit)
Maybe not so long, like a quick guide or a serie of videos.

Maybe you should reposted here
