I recently flagged Pearson's comment on this post as obsolete in response to Tildal's call for obsolete comment flags:
Edit your question and put it in. It's pretty common to edit questions after the fact to add such details. – PearsonArtPhoto ♦ Aug 7 at 17:08
This comment was in response to Hash responding to Pearson asking for a source. Hash responded with a link to the source, and Pearson asked him (?) to edit it in.
I checked, and the post was edited and the source added. Why is this not an obsolete comment?
