The more I've delved into free and open source, the more I've seen what isnt normal: stuff that isnt designed out of the box to be eye-candy. Seeing the complete opposite side of the spectrum, its clearer that Facebook isnt just eye candy, good animations, timely pop-ups, and perfectly targeted ads. It's everything and more. The addictive tactics have created an emergent highly addictive quality. And dont even get me started on Instagram.
