Some of the comments on Gil's recent question are flagged as not-constructive.
They are not literally offensive or rude, they are not irrelevant to the question, but honestly they don't seem to contain anything that anyone who is a little bit familiar with the topics would not know (and surely Gil is more that a little bit familiar with these topics). In other words, anyone could have written a similar comment. They don't add any new information/knowledge.
The reasons for flagging a comment supported by the software are:
- rude or offensive
- not constructive / off-topic
- too chatty
I am not sure if any of them applies to these comments (maybe "too chatty"?). On the other hand I personally feel that leaving such comments are inappropriate and possibly harmful to the usefulness of the site (as I understand, people don't come here to read general comments that anyone would know or could find out by a simple Google search but to ask question from people who have expertise on those topics).
On cstheory, we generally don't remove comments as long as they are not really off-topic or clearly rude.
Is leaving general comments that do not add any significant information to the question OK?
Questions that are answerable by simple Googling or looking at the relevant Wikipedia article are considered off-topic on cstheory. Should these criteria also apply to other posts on the site like comments?
