Serious note: How much Bretons actually Speak Breton? I know wiki says c200,000-300,000 but that seems awfully high really.
Otherwise. Celtic Languages yay!
These things are always difficult to determine - given than there is a difference between knowing a few words, being able to coverse, being able to write and understand and 'lying through your ass.'
I know a few phrases in Gaelic for example (less than I did when I spent a few months learning it at school). Yet that is deemed more 'impressive' than the fact I have very good knowledge of spoken and written 'Middle Scots' (pre-Union Scots)
Damned constructed cultural history 
Well I understand. According to last census roughly 40-50% of the Irish population answered 'yes' to the question on Irish language use. Which just shows how much liars there are in Ireland. Obviously here I'm not looking for precise figures, just reliable estimates.
Completely agree with the last sentiments in your post btw.
