Blah Blah Blah Day (17 April)

What I learned:
- "blah" is barely 100 years old (orig. U.S.) - first attestation (as noun) 1918, first triple-bla 1924.
- I thought at first this might be a day in honour of an Iggy Pop song (and album, 1986). But...jeez, there are a lot of songs by that name - one by Gershwin even!
https://en.wikipedia.org/wiki/Blah_(disambiguation)
- I would have spelled it "bla (bla (bla))". The French seem to agree:
BLA-BLA  or  BLA-BLA-BLA  'Verbiage'  (Larousse)
Oh! The day?
"...the aim of this day is to increase meaningful communication, to appreciate the value of everyday conversation, and to foster achievement."  (Huh???)
"It was created in 2006 by Ruth and Thomas Roy of Wellcat Holidays and Herbs with a very positive set of intentions."
Enough.
Oh, it's also International Haiku Poetry Day (Crystal).
