When I started out as an academic, I believed it was my duty to do research and publish it, but I found self-promotion tacky. Well, I guess that's all changed, and now I make things available on my website and on ResearchGate, just like everyone else. I accept that we have to promote our research, and we can't just sit back and hope that somehow people will find it.
Now, as part of my role as Webmaster for my Faculty, I have been tasked with creating and maintaining a 'News' page in the faculty website. (See here).
Is this the sort of thing an academic should be doing? Well, I suppose in the modern world where universities have to promote themselves, just like businesses, it probably is. And even if it does take time away from research, I have to accept that this sort of work is what we all have to do. (Anyway, it beats being on another committee!).
Maybe some people will find it interesting and useful, who knows.
