Many content-centric products have been moving to a magazine or card style layout, popularized by apps like Flipboard and Pinterest. Both Flipboard and Pinterest are beautifully designed products, but our studies indicate multi-item-per-row grid layouts deliver inferior results to single-item-per-row list layouts for our particular design problem.
These relative results may be unique to us, but we nevertheless publish them here in case they may be relevant to others considering the tradeoffs involved in list vs. grid designs....
Good argument for moving away from grid layout back to lists according to usability studies by Prismatic.
