The comment I wrote was a pithy, uninformative comment that was misleading about the content of the article (I suggested that the author just didn't understand ambition very well, but she's clearly not talking about general ambition; she explicitly distinguishes people who are in it only for riches.) Worse, it had 7 upvotes almost immediately, meaning that people were reading it and getting a wrong and unfair impression. The reply added nothing except to correct me. I don't feel like anything was lost.

You could say that I should leave it in case someone else makes the same misinterpretation. Perhaps I should, but I would not anyway. I don't care to represent myself with incorrect or useless comments documenting my stupidity; I would prefer to remove them from the record and let people who know what they're talking about go ahead.
