A baked potato stuffed with Chili, sour cream & cheddar is a complete meal.
We usually make it for dinner at least once a month.
I’ll eat some of the skin because of the nutrients.
Cut it in half, longwise. Cut a grid into the flesh. Add butter, and likely some combination of cheese, bacon, and sour cream. Give the butter and cheese time to melt, then…eat it one end to the other like described in the OP.
Melt it in a spoon with butter and shoot it up.
I’m scratching your name off the list of my Party Guests.
The Baked Potato Stall at the Royal Highland Show, near Edinburgh, used to have a sign next to it which proclaimed:
Every skin has vitamins in
Not to eat it is a sin
But if in doubt
Don’t be a lout
Please put your leavings in the bin
Ah, any other way is disgusting, so why am I having a laughing fit?
Innards first, then the skin. Butter is the only topping I use now. I miss the days where I could eat them with bacon and cheese in college and not gain a pound. Baked potato bar was a thing at my college dorm cafeteria.
End to end, like a hot dog. That’s right. It’s an excellent self-contained food package that way.
Either I cut it up and eat it in pieces or I eat the innards first and then the shell.
Sour cream, butter, bacon and cheese are needed obviously.
Oddly, I seem to be almost the only one who doesn’t really eat baked potatoes. I like them pretty much every other way, but baked doesn’t do it for me.
I don’t eat them often, but I was craving a baked potato yesterday. I added sour cream and butter and chives and jalapeño slices and a little radish. Oh and some blue cheese.
It was quite tasty. I just mushed it all together and ate it with a fork.
Margaret Thatcher once scolded a feller at an open air market who was selling potato peelers. “You don’t take the jackets off, that’s where the vitamins are!” (Thank you Mrs. Know-it-all.)
I thought I was the only one!
Well, she was a research chemist… 
The last time I worked in an office (in Moscow), I’d spend every lunch break at one of these on Pushkin Square:
Kroshka Kartoshka (loosely translated as “Potato Bambino”) serves baked potatoes with your choice of fillings. Street food that’s very cheap and very, very good. I wish they’d open at least one in Toronto… 
Had my first experience with spuds as fast food in Edinburgh way back in 1976, near the top of the High Street, I think. Up to that time, I’d never seen such a thing in the US.
I’ve never had a baked potato that wouldn’t scorch the shit out of my fingertips if I tried to eat it that way.
I eat the innards (typically just buttered well, with LOTS of black pepper), then the skin.
I always eat the inside then the shell. But I note that only one person mashes it up with the toppings and then eats it like a burrito. I would call it a deviled potato and I think I will try it the next time I have a baked potato. Yum.
Cottage cheese seems to be a fairly common tater topper among my extended family. It might be a central U.S. plains state thing.
Mostly this, except it’s the top half of the skin that I’ll leave behind. The bottom half is usually crunchy and delicious, while the top tends to be less so.
This assumes a thick-skinned russet. Most all other kinds of potatoes have a thinner skin the which I’ll entirely eat. The russet skin can sometimes be a little too much fiber for me, so I stifle myself.
Also, the OP should have seen my Grandfather eat an apple. He’d start at the blossom end and work his way up and through, spitting out the seeds as he hit them. Nothing left but a little stem.
