I'm quite polite, but I haven't noticed significant upvoting of the thankyou nodes I posted in my last query. One of them was downvoted, although it did say that the previous poster didn't successfully answer my question.
in reply to What do you think about "Thank you"-nodes?
However, I think thankyou nodes are useful to indicate whether the answer was successful. I don't really expect them to be upvoted though, as apart from giving some feedback they often don't contain information strictly useful, so I think they should be neither up or downvoted.
