I believe that it played a huge role. Although, I feel that you could still start a successful iOS blog today, you would have to bust your butt to even come close to sites like http://www.raywenderlich.com. Believe me, I've tried on my blog a while ago, but it's extremely hard to keep up a relevant and popular iOS tutorial site, especially with how fast Apple is moving.

That's not to say that you can't grab a piece of that market. When I was blogging there were only a few thousand iOS developers, now there are hundreds of thousands. So there is more demand.
