A lot of people made new years resolutions about using social media less. So now we have an optional daily time limit! It's in https://piefed.social/user/settings. Bear in mind that it only counts time spent with a PieFed tab in the foreground - when you switch to another tab on another website to read a news article the timer stops. So you might need to set this lower than you think for it to be effective.
One nice thing about the fediverse is we don't need to optimize for addiction and try to keep you here longer than you want to.
The warning pops up with every page load so just clicking through it once won't work. It's for your own good!
Ah ok. It should be pretty easy to make it possible to put things like 0.5 in there, in a future version.
