There are great differences among Wikipedias.
Apparently, sk.wiki and pl.wiki are the only Wikipedias where standard
edit summaries buttons are used, and where edit summary usage is about 90%.
Wha to do you think? Are those buttons useful, or maybe they make edit
summaries more similar and pointless? Do they increase usability? Should
we introduce them elsewhere?
