in reply to What do you think about "Thank you"-nodes?

For a shorter thread, with one particular answer, a thanks reply flows well.

For larger threads with multiple answers, thank-yous would quickly start to get spammy. Appending the thanks to the original post may be a better idea so that future readers can see right away that there were some good answers and find them faster.
