I use multiple methods for storage/display.....I've been building/buying/collecting/modding for over 20 years.
Below is a good general example of what most of my guitars live

My main method is whatever I'm using the most at the moment gets it's own 2 stands in front of the big rack, the other most used guitars go into the multi-guitar racks behind them. The guitars I use the most often live here in my man cave.
In the livingroom, where my live rig lives, I have 2 more guitar stands for display/decoration, usually some of the secondaries go out there and get changed every month, sort of to fit a theme of sorts (ie like X-Mas color guitars for X-mas, summery colors for Summer, whatever).
I also have another 3 guitar rack in another room where my Dean ML-X, Acoustic, and my wife's Strat live. One special guitar from our wedding gets hung on teh wall, and comes down occasionally so I can get some "white background" pictures for websites/posting whatever.
And all stay perfectly setup, in tune, and ready for action at a moment's notice save for a small handful at the back of the main rack where I have my next-in-line project guitars sitting (barely visible way far in the back of the photo).
