because on typewriters you could fit 70 characters on a typical line of 8.5 x 11 paper with 1" margins so 140 = 2 lines of text.

140 characters and spaces will allow one to produce the most economical couplet in iambic pentameter possible.

or I could be full of doodie.

digimom that deserves a banana dance!

ancient number with magical powers???

maybe, limitation size of . . 140 8-bit en.wikipedia.org/wiki/Te...

it might be the text message limit for cell phones too.

Doesn't 140 characters on Plurk seem like more characters than on Twitter? Wierd, but I always feel like I have more room here.

Budtheteacher said earlier today it's SMS limits. DK what that means, but everyone said "Ahhhh."

More room because the names aren't counted as part of the 140 characters.

to kmulford that SMS is the terminology for text messages.
