These days you don't want to get into an argument with someone who stays up all night blogging.

But seriously, if you google "who buys ink by the", the first hit brings you back to this very site. Try this link, and you'll find that it's attributed to both Oscar Wilde and Mark Twain: www.phrases.org.uk bulletin_board 39 messages 719.html

In the form 'Never pick a quarrel with someone who buys their ink in barrels' it was attributed to Benjamin Franklin by The [London] Observer, 27th July 1992. No proof though.
