Quoted in Getting Real is a passage by Jef Raskin about avoiding "feature blight" (
http://jef.raskincenter.org/unpublished/widgets_of_the_week....). The passage suggests too many features is a bad thing and that the best way to avoid that pitfall is a very real and constricting deadline. My question is that once you've launched and you're able to afford a more liberal deadline, how do you keep feature blight from creeping in?
37 Signals was noted here recently for refusing to implement suggestions until there's a critical mass of users looking for them, but is that the "best" way to combat this issue?
Feature blight is a separate issue. It's good to try out lots of stuff, but you can't just vomit out feature after feature -- you have to iterate. After you release a feature, watch how people use it. If they're not using it, tweak it or axe it. Features need to earn a permanent place in your app.
