I am particularly appreciative of the blog author's transliteration of the phrase, respecting the Hebrew (technically Aramaic in this case) pronunciation of his yeshivish background and not choosing to "modernize" for a broader audience. I am curious how common the "ay" is these days as opposed to "oy" - I don't know if I've heard it in a long time. Which part of Europe does it come from, and which yeshivos and communities are still doing it? Anyone know? In general, I'm fascinated by the different ways the language evolved before Ben Yehuda's revival and standardization and I find it frustrating that in some corners of the Jewish world a conscious decision was made to abandon this natural fragmentation in favor of a standard.
