This will give you a short time spike in installs. Nothing wrong with that, but it doesn't last and you can't play that card more than once.
Yes, there is a bit of a chicken/egg here, but getting _some_ installs for an app really is not that difficult.
That will get you your 5 minutes^H^H^H^H seconds of internetfame already. However, it will only create a short popularity spike and you constantly have to invest in promotions to keep that up.
The blogpost doesn't tell you to put ads for your other apps into your apps (that would be stupid!), but to think of ways in which they can complement each other. That way you get effortless crosspromotion, can touch vastly different traffic sources and channel users to your main app.
