I think this is good advice and an accurate view of how to get ahead (as much as I hate to admit how much of an advantage everyone with deep pockets has). It's definitely hard as a little guy to get started but there are ways to get some attention if you can afford to invest in buying installs.

There's of course Facebook mobile app installs, but a lot of other ways to get installs also that might be more cost effective. Some others: http://www.appoday.com/#developers http://www.curios.me/

Best of luck!
