As far as I can tell, the upshot after scoring a million tweets is that the only one with all 26 letters was just

"?????????????????????the quick brown fox jumps over the lazy dog??????????????????"

This is considerably less interesting than I hoped it would be. (And a little surprising! That's a lot of data.)

Isn't it a bit silly to throw away every single @<user> tweet? Imagine I'm having a twitter conversation with my friends about who can make the best pangram and this data is ignored just because we're tweeting @ each other?

I'm guessing that the majority of tweets will reference a person. How about just stripping that @word from the tweet?

At first I thaught "Searching Twitter for a better pangram" was the pangram.

I'm stupid.

Not easy to remember, but I recall this phrase appeared in the Guinness Book of World Records for shortest pangram: "Veldt jynx grimps waqf zho buck."
