I realize that short "thanks!"-style comments are not encouraged on SE sites (Reference: What is the etiquette about leaving short thank-you comments?).
However, people still post "thanks!" comments (sometimes while saying something else about the answer). When I see someone say "Thanks for the help!" in a comment to one of my answers, my first reaction is to want to reply with "Glad to help," or a similar phrase.
I haven't been doing so, as I feel it would be discouraged for the same reason "thanks!" comments are discouraged (noise, etc.).
Am I correct in not replying to these comments with a "Glad to help"?
Extending this, could it be said that all comments posted strictly to be "polite" are discouraged? (e.g. comments consisting only of compliments, etc.)
