Edit: Wow, really weird. If this response seems to not make sense its because I responded to another comment that got deleted, and this somehow got transferred under this comment. Sorry for that, but I'll leave it here. I think this is not gold rush mentality taking place. I think quite the opposite, deciding to work on these problems may be hurting this community. For starters, this is not traditional startup community we are talking about, which I think is really important to realize. This is what the Mac indie community has morphed into (now the iOS indie community), which is very rarely looking to flip (not that they won't when given the chance of course, just trying to point out the context these apps are being created in). On that note, most people are trying to make popular apps that generate profit, not some long term vision like Facecbook or something. And given that, I find it very hard to believe that it makes economic sense to work on these sorts of things: the author said it himself, the economics of making a weather app seem to be the number one thing holding him back, because there are just so many. These apps take a long time to make and a lot of care, and if you're going to invest that into "calculator", the returns probably won't be great. The opposite side of the spectrum is often the web world: hugely ambitious idea churned out super quick (with an unfortunate lack of attention to detail).
