Touchgraph (Facebook power grab)

Touchgraph was easily my favorite F*book app ever. But whether you’re a company like Touchgraph, or just an individual like you or me, when you build your home on somebody else’s property, you always have to be prepared to wake up one morning to discover that your home and your belongings don’t exist anymore.

F*book is a proprietary, closed platform that changes its TOS to suit it’s marketing & monetization interests. You are not the customer, you are the product being sold at the slaughterhouse auction.
