In the more subjective discussions comments frequently wander into the realms of discussion.
While SO/SF/SU aren't intended as discussion sites, this isn't necessarily a bad thing, however are there certain ways people "should" behave when this happens.
My view is that the basic rule should be that the answer (rather than the answer and the comments) should be the key thing. As a result where possible/relevant all comments and responses should be merged into the answer by the answeree - effectively enhance it answering, or at least commenting on, criticisms.
I did this recently and then went and deleted my comments on the thread - I thought this would be neater and the comments chain was getting longer - however someone pulled me up saying that certain comments now didn't make sense.
I get that and wondered if anyone had thoughts on how best to handle long comment chains?
Enhance the answer and leave comments, enhance the answer and remove comments, take the number of comments that the question is too subjective and close it, something else entirely?
