The crazy thing I did to fix Yosemite performance

Yeah, I've been a Mac user for a long time. I don't just leave stuff in
my Library folder forever, nor should anyone. Free apps like CleanApp
help remove everything when you remove apps. Otherwise, you can still go
into your Library folder and delete settings and preferences as needed.
You can unhide the ~/Library folder with:
chflags nohidden ~/Library
The idea behind backing up and restoring my user folder is so I don't
have to re-configure everything after wiping and reinstalling OS X.
This is actually something Apple does very well. When I restored
everything, and rebooted, every single one of my most used apps (Adium,
Thunderbird, Chrome, Tweetdeck) launched perfectly just like they were
before...without having to go through and re-setup all my accounts.
The "most users" you mention should not just blindly attempt what I did,
not without researching and planning it out beforehand. I consider
myself to be rather experienced, and know how OS X works on the
frontend, and backend in BSD (Darwin).
