I think we all realize (whether we write or not), for writers, it's rather frustrating when there is no/little feedback. Hard for the writer to figure out what's going on there. Is it perfect, so no one feels the need to add anything? So horrible that the readers run screaming and will never come back? Too long or dense to plow through? Readers like it but just don't have the time to say anything about it?
For a lot of the online world, extensive feedback is just not going to happen. If you look at a Social Technographics ladder - http://www.jeremyfloyd.com/2011/08/w...ure-talkin-to/
you see that the biggest chunk of people just read. Then a smaller chunk just hit "like" (or vote for stuff). Then an even smaller chunk review.
