No probs. I suspect that it's partly because some of them are a nightmare to get to - eg Ararat (Turkey) is in a military controlled zone and you need a permit from memory, others aren't worth climbing, I mean, the highest peak in Denmark? Do me a favour. And then, of course, being Brits, we're essentially insular and scared of crossing the bit of water between us and the rest of the continent.
We do have a variety of serious collectors though, the Munroes I'm sure you know about, but there are all sorts of sub-divisions and sub-sub divisions. And all the alpine 3000ers and 4000ers are popular.
