What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 133 Stack Exchange communities.

I can't tell you how many times I've seen a comment that simply says "+1 for [insert quote from answer]". Here are a few examples:

  1. Why do we have reinterpret_cast in C++ when two chained static_cast can do it's job?
  2. Why do we have reinterpret_cast in C++ when two chained static_cast can do it's job? (different comment)
  3. Regular cast vs. static_cast vs. dynamic_cast

Do comments like these contribute to the overall good of the stackoverflow community?

-1 because users can have comments match /^[+-]\d+$/ as many times as they'd like, and there's nothing you will ever be able to do about it. –  Jack Maney May 24 '13 at 18:44

I sometimes see such comments used to draw attention to an important part of a long answer. In such cases, it may be appropriate to edit the answer to make the point stand out more so that the comment is no longer required. –  hammar May 24 '13 at 18:52

I don't think there's anything particularly wrong with this post, but I voted to delete since it's a duplicate and the comments make it mostly noise compared to the other threads –  Michael Mrozek May 24 '13 at 19:19

The examples you have given don't add much to pretty much every user except for the answer poster - a bit of info so they know why they got a specific upvote (though not even that, on occasion).

Flag as "not constructive / off-topic".
