Colleagues Blogging (now behind bars)

Last week I noticed that two of my colleagues Michiel van der Heyden and Ale de Vries from Science Direct have started blogging. I started this post to mention about their blog and to direct my readers to their blog to see what they are talking. When I went to their site I noticed this post stating that now they are going "behind bars". I don't have a clue why they went behind bar?
