Wow Apple is really serious about shutting it down. I suspect we'll see some sort of backlash from AppGratis. I never really got those app discovery apps anyway... That's what the App Store is for IMO.
The AppStore itself is awful for app discovery and browsing, you get the "paid" to float to the top "recommended" apps and thats about it, Usually i read reviews of apps, or google which apps do a job then get the app name and then Finally fire up the app store on the iPhone/iPad and search for the one app i want by name.
