I did a survey on #mastodon a couple of days ago, asking what the longest you ever had a single linux distro (as a daily driver) running w/o switching, re-installing, etc.
The results surprised me - especially now, since I just did a fresh install of my laptop and really appreciate the opportunity (provided I have the time) to re-explore old apps, maybe try new ones, discover new features or changes that I had previously been oblivous to AND to install/setup certain things the 'right' way after having gained more insight and experience.
It's incredibly easy to setup a new Linux instance nowadays - and is very rewarding!!
