- easy to use with multiple people
- easier to manage for multiple people
- easier to backup (since you don't need to do backups per device)
- less hassle when you switch personal devices (or reinstall a laptop for ex.)
- You own your data (instead of a mega corp.)
- Less dependent on internet connectivity*, power outages*
- Its a nice challenge
- Its fun (some of us like the self inflicted pain that comes along with it ^sometimes)
*limited to outside factors like how much you actually self host and how much backup power you can store/generate.
