Like, I get comments from people telling me it's weird I always try to peel potatoes like I am trying to make the worlds longest 1-piece potato peel. To me it feels way for efficient and fun to continu down a potato in 1 peel, while circling around it, instead of randomly scraping a hundred different pieces of peel off and having to reintroduce the cutter knife to the potato for every piece.
Some recipes seek the smoothest consistency. Skin interferes.
If you aren't cooking that specifically, just wash the skin.
Do you mean there's something other than roasted and mashed?
Oh... How could I forget gnocchi?! That wondrous improvement on pasta
