Absolutely the best way to learn. Seeing how someone else sets up their anvil or organizes their tools can fix a problem you didn't even know you had. Picked up a neat trick for drawing out a taper last year just by watching how they held the hammer. Every shop has its own little fixes and it really makes you rethink your own space.
It's crazy how just watching where someone hangs their tongs can give you a whole new layout idea for your own forge. You come home and suddenly your whole workflow feels different.
