I wonder how long is this going to last. Lately I been hearing more about startups that provide tools and services to make apps than about startups that make actual apps.

I think that might be a sign that this gold rush it's on its last legs. Too many devs got tired of trying, so the question now is how long until the vast infrastructure of app-dev startups starts to crumble due to the old offer>demand imbalance.

Pickaxes sure got a lot cheaper when nobody was looking for gold anymore...
