I agree. I think it's important that a lot of the people with lackluster sales or disappointing results should take a step back and be honest with themselves about whether or not their app is actually worth buying. There is plenty of moaning and belly aching online from iPhone developers who are upset their apps don't sell well (such as this semi-famous one: http://gedblog.com/2009/09/28/losing-ireligion) but few thoughts from people willing to analyze their mistakes and faults.
Interesting. A bunch of bellyaching because a game isn't selling well - and I can completely understand /why/ it didn't sell well. Heck, it's free and I still won't install it.
