Oooo, ahhh, it's time for food porn

Social media has changed the way we eat. The first thing many of us do when the platters are laid on the table is whip out our smartphones and start taking photographs.

The next thing we do is to log on to WeChat, Twitter or Weibo and post food shots online.

This compulsive urge to show off has raised the ire of some Michelin-starred chefs, who criticize amateur food critics who allow their food to grow cold while they let friends and fans know exactly what, where and when they are eating.
