I suppose I'm a member of that indignant mob, though I have no problem with fixing spelling errors or linkbait or inflammatory titles.
But the flip side of the loud indignant mob is the quietly indignant mob; a few days ago I submitted an item that I thought might be worthwhile, except that the best-formatted (easiest-to-read) source, nbcnews, also happened to be the one with the worst title. So, I used the title for the same article from the AP instead, and within a few minutes a moderator had mindlessly changed it to match the crappy, inflammatory title from the article.
I didn't bitch to anyone though, because it's clear that nobody's mind is going to be changed, but I wondered why HN doesn't just automatically pull the title from the submitted article. There's really no point in my putting any effort at all into a title.
obtw, a good rule of thumb in customer service is that for every complaint you get, there were 10 other people that had the same problem but didn't put the effort into telling you about it.
