[Tagging] wetland=bog, why only "receive their water and nutrients from rainfall"?

What does "fen" means to you?
I've a fairly good idea what I think it means, and I'd never or almost never tag it as a natural feature (though it may have a name, and the natural features within it may have names).
I'm a native English speaker (though not native to a fenland area)..
Could you come up with some examples of things that are currently tagged as bogs but shouldn't be, or aren't tagged as fens but should be (in the UK and Ireland would be helpful to me, as that's what I'm going to be most familiar with, but obviously other places will be helpful to other people).

Well - I don't want to pass judgement here on the articles - I only
provided the link because it contains a well readable description of
the differences. That being said the bog article is quite clearly not
a shining example of quality in Wikipedia.
The established values for wetland=* in OSM are mostly based on wetland
classification schemes common in North America which generally make the
distinction between bogs and fens as indicated. You can find this for
which is of course somewhat biased towards the types of wetland common
in the region. There would be no problem in using more precise tags
more clearly distinguishing the nuances in wetland types. There is
already some limited use of wetland=string_bog/palsa_bog/raised_bog.
Current tag use indicates severe underuse of wetland=fen and overuse of
wetland=bog. Probably more than half of what is tagged wetland=bog is
