From time to time, I go through comments I made to see if they're still relevant and adding value to the site.
If I delete a throw-away comment (I made), I flag any replies as "obsolete". But how about comments that sparked a bit of discussion? If I feel my comment no longer serves a purpose, should I just delete it and flag all relies as "obsolete"?
An example would be
where I deleted a comment on the boy scout's salute being three-fingered. Now the comment by @Phantom42 following it, may be interpreted as referring to something in the original question.
