I recently had an opportunity to publish a "correspondence piece" in Nature journal. The piece is still under development. I just wanted to ask, if publishing a piece in Nature journal is prestigious; especially in my hunt for a new postdoctorate position? Thanks for your help in advance.
edited for clarity It depends a bit on WHY you are asking, since you mention the hunt for a postdoc. Do you want to describe it/mention it somewhere as a piece in the prestigious journal Nature? Or as a prestigious contribution? I would stay away from using the adjective 'prestigious' myself.
In the same way that all individual papers should be evaluated based on content and merit, I would also look at this piece in the same light. What is it about? Is it related to the work you did for your PhD? Did you take the initiative or come up with the idea for this technical comment? Did you write most of it and is a figure with your data included (as I think is often the case in a technical comment type letter to the editor)? In that case, you may want to mention it in the motivation letter as suggested by Moishe because it does mention contextual thinking and critical contributions to your field of research. But then mention WHY it deserves mention and stay away from calling your own stuff or the journal prestigious. Let the reader make up their mind about that.
If it is not directly related to the bulk of your PhD or the field your searching your postdoc in or you did not conceptually contribute much then I would just list it on my CV as any publication. Apart from the fact that it isn't peer reviewed, so I have a special section for that (non peer reviewed articles, but you can also call the section 'correspondence and opinion pieces' or something as it expands over the years.
I disagree with Andrew that it is the same as a news article of TV segment. That would go under publicity or media attention, this is scientific writing for a scientific audience.
