I would like to start a discussion about the different customs that exist in research groups when it comes to the writing of articles. This is inspired by an experience I have had as a postdoc.

I consider my PhD time as the period when I was first exposed to writing scientifically. I think everything went typical: my first article was a real struggle, but afterwards things got easier. Looking back I consider my PhD time as the time I really learned to write in a structured way. And I have come to view this experience as essential in the development of a young scientist.
