Use and extinction of the tradional pronunciations

[squee100]

I do use Askenazi pronouncation, in my day to day life, when teaching I use usually modern Israeli, but my daughter I am gonna teach Ashkenazic, there is advantage from the understanding point of you.

I guess you are not contributing, because Ladino is dead, Yiddish is alived, you need to have real B I G group in order to achieve to keep it alive

I don't want to relegate any of the traditions mentioned in the encyclopedia I linked to the dustbin of history. Am I going to have to if the Jewish groups that use them (none of which I'm a part of) stop doing so?
