Here's an interesting new
business model: AppsBar
I haven't tried it, nor will I, but it claims to let non-technical folk build apps interactively for Android and IOS devices, and then publish them to the Apple or Android markets, all for free. AppsBar gets to insert advertising into these apps and collect the revenue from them.
That would be a fair bargain, IMO.
You won't make any money off of your AppsBar app, but you'll surely be guaranteed to get plenty of spam forever after.
