About a week ago I posted a haiku on Twitter. It was one that I wrote as part of my plan to write a haiku each day this year.
Then I was surprised when this reply came back within a day or so, which incorporates my middle line into a haiku apparently composed from others on Twitter.
It prompted me to think about the scripts and bots that populate Twitter and where one draws a line with collaboration and begins to call it plagiarism.
Then I remembered something about recent poetry controversies concerning lifting lines from other works in the guise of quotation.
