I don't know about the rest of you, but I actually learned a few things from this thread. That said even though this thread did take a few strange twists and turns.
It is good to be challenged a bit to improve playing skills.
That said, I always have to keep in mind what I can do to improve the experience of my audiences.
For me, that means adding songs that are requested, and finding ways to involve audience members as my audiences benefit from active involvement in what I do. Plus the AD's I deal with appreciate that.
FWIW, I did try some new chord changes on Georgia. Some worked but some(due, I think, to the way styles work on my arranger) just didn't work.
It's definitely easier to involve more complicated chords on my guitar than on my arranger.
