*NOT a CFP!* ;)

Hello all!

I have been thinking about using the criterion of a minimum number of bytes to evaluate the students' edits for my next course - together with content, of course. This came up because I noticed some students were editing as little as possible, and this time I want the whole group to start new articles from scratch. 

Has anyone used this approach? Pros/cons? What would you consider a reasonable number for the minimum of bytes in the final article?
