I am from Mainz, Germany, spent a couple of months in Warwick/Coventry (England) and in the Bay area. Graduated in Maths (Dr. rer. nat.), became an IT guy. Used to work in a group of artists in the 80s and early 90s producing noise-music and sound/light-installations. Have some interest in Linguistics and Philology. I like various kinds of music, European classical, modern, South-Indian classical, Japanese, Bluegrass, Jazz, Soul, Korean etc.
What Germanic languages are dying?
East Frisian (1500 to 2000 speakers left); North Frisian (still 8000 to 10000). The German dialect isles in northern Italy (Mocheno, Cimbrian) are dying, but they might not count as languages. Similarly Frans Vlaams (almost not spoken anymore in coastal France near the Belgian border) is a Dutch dialect, but extreme from a Dutch point of view. But then, the Frisian dialects can be seen as part of Frisian, which as a whole is not yet dying, with many more speakers of West Frisian. Still, mutual intelligibility between those is poor.
Yiddish seems to experience some revival currently, but still I am not sure about its destiny.
And - thanks to Daniel Ross, Scots should be mentioned as well.
