This Mastodon setting is really important:
1. Log into your server's website
2. Go to ⚙️ Preferences (or Settings)
3. Click "Posting Defaults" (on mobile click ☰ in top right, then "Posting Defaults")
4. Make sure "Posting Language" is same as language you post in most often
5. Click "Save Changes" at top
This matters because many people use language filters to only show posts in their language. If your setting is wrong, your posts may be hidden from people who can understand them.
@FediTips this is why I have a filter that hides posts with frequently used not my language words and another to hide posts with non-latin alphabet characters. Dunno, is setting Posting Language too privacy invading for some?
