I remember this thread http://www.rationalskepticism.org/general-language/gaeilge-should-we-keep-it-t19024.html and have just come across this on the BBC website:

Manx: Bringing a language back from the dead

http://www.bbc.co.uk/news/magazine-21242667

And whilst i do not speak Manx (being a come over and no incentive to learn) there has been a increase in the interest, and consequent teaching, of Manx in the local schools, one primary school teaches purely in Manx.
The BBC is translating a children's TV programme into Manx http://www.bbc.co.uk/news/world-europe-isle-of-man-21284716. From a local's point of view this can only be a good thing.

This happened with Gaelic in Scotland years ago. We have some Gaelic TV programmes available on the BBC, and BBC Alba is all Gaelic. I don't think the public really bought into it in any big way, There may have been an initially large uptake of Gaelic lessons but I'm not sure it lasted very long. Inverness has it's road signs in English and Gaelic but it's pretty much just the Islanders that speak it.

I have a friend here who taught herself Manx for no apparent reason other than interest. She went for a visit there a year or two ago and was very well met by the locals. Apparently could never get a round in.
