Should fediverse stay a niche "project" for idealists? Or should it become an actual alternative?

When not sure, this site explains it well: https://choosealicense.com/

I guess that's not enough. Software needs to be more self-explanatory.

AFAIK one should also drain the battery to zero once a month and charge it fully (100%!) to recalibrate the battery capacity.

You can and should use then the device to get below 80% again.
