Because we haven't received a single complaint from users or seen any decline in the way people listen to or skip music since implementing that feature, and like 4 people here today complained about it. Not to mention, just generally there is a ton of new Feedbackify today complaining about things clearly for the sake of it.
Edit: One of the complaints is so golden that it's almost a blog post in itself, and the person said they came from HN.
I was wondering if there might be some sort of sampling bias at work. It sounds like it still might be, although you mostly have those bases covered. Specifically, people who already use the service know where the feature is, so they know what they need to get rid of to find it. Perhaps more importantly, they know that the feature exists, so they'll be more persistant in finding it. Not having/finding a skip feature is probably a dealbreaker (it certainly was for me, until I came back and saw this), so it would just manifest as some new people not sticking it out for very long.
But maybe that's not it. My other theory is that the less adept a computer user is, the less they're able to ignore popups like that. I've noticed that many less experienced computer users have an almost pathological need to get rid of any sort of dialog box, message, popup window, etc. More advanced users tend to just ignore anything that isn't directly interfering.
I think it's the latter, and there is definitely a possibility that it's a behavior in usage that makes the difference. But I don't think we should rule out that the HN crowd just likes to nitpick. ;)
I definitely couldn't find the skip control after quite a bit of looking. Maybe I just had a dumb moment, or it's due to how I approach these things, but mine, at least, wasn't due to nitpicking! Can't speak for anybody else, of course.
