Customers spend the majority of their time on the top 10 digital experiences then check their local news or car dealership and get a reminder on what the rest of the internet is like.

The advent of digital retailing has pushed the feature stuffing to the max. We need it to swing back towards a cycle of clean designs and better implementation of supplement applications.
