Doesn't really alter much.you might want to go back
anticipating something like this, I re-edited
The amount of time spent on something doesn't indicate it's actual worth.
How much time, effort and paper is put into train spotting? (As a hobby - not the existence of trains themselves).
Does that make train-spotting a valid (whatever that means) practice?
Any more valid than, say, military vehicle restoration (which has fewer devotees/ written materials).
