Is your Mastodon timeline too empty or too full? Are you seeing stuff you don't want to, and missing stuff you do want to see? Is your timeline overwhelmed by someone who shares too many posts?
These and lots more timeline problems are solved in the "How to customise your Mastodon timeline" guide:
I'd like to be able to follow hashtags without seeing posts in languages I don't understand that also use those hashtags.
#Mastodon language settings don't help with that & after having a timeline 30-35% in languages I don't know, I've ended up muting hundreds (maybe thousands now) of accounts.
In fact, I've started looking at my alt account's timeline (exquisite.social) first because Mastodon's lack of hashtag migration means my timeline there is only people I follow, & only afterwards going to my original account (ohai.social) that includes followed hashtag posts.
Are you sure you've selected the option to filter languages, rather than just setting your own interface language? (More info at https://fedi.tips/setting-your-language-preferences-on-mastodon-and-filtering-out-posts-in-other-languages )
The language filter should help at least somewhat, but by definition you won't notice the posts it is successfully hiding.
There is also an automatic language detector, and it tells people when they've got the wrong post language setting, but it's not reliable for short posts so that's why it doesn't override the person's setting.
Yes, I've set the "Filter" languages, not just "Interface" language.
(Preferences > Other > Public Timelines > Filter languages)
And many of the posts in undesired languages (in my case, 95% German) have been quite long, hundreds of characters.
I wonder if following a hashtag trumps/bypasses the language filter.
Hmm... in that case, I'm not sure what else could be done directly there 🤔
One workaround might be to use the "filters" feature to try to filter out posts containing German word(s) that appear in the posts you don't want to see ( https://fedi.tips/filtering-your-timeline-to-hide-posts-on-mastodon ).
About the long posts, some interfaces and apps shorten them automatically with a "read more" link. Are you seeing the posts full length?
Re filters, thanks, I might try that workaround. Hopefully, it'll save me muting a few hundred more accounts.
Re display of long posts in undesired languages, my timeline has had both: long posts shown complete & long with Read More.
