Ultimately, it's for people to enjoy walking in their own way. If they want to log every mortal thing, that's fine. Personally, if I am walking a hill, I just want to be sure I get to the top, so it's nice to see a trig, if there is one. Otherwise, I don't care whether it's a Munro or a Nuttall or whatever. I have no idea how many Wainwrights I have done and couldn't care less.
I can see why people might like stamp collecting or watching birds but train spotting?
Oh, and nothing gets ironed!
