Should I mention my co-authors while tweeting about our publications? Assume we have a paper published in a conference or journal. Should I mention my co-authors while posting some content of the paper (or just paper's link) on Twitter or Facebook?

Let's assume I am aware of their Twitter or Facebook accounts.
It would be a polite thing to do to at least link the co-authors, for example, something along the lines of:


  Paper title, paper link, #co-author


It also depends on the amount of space available in your tweet - their names will be written on the paper itself in any case. At the very least, let them know that you are tweeting/posting the link/paper, which would give them an opportunity to retweet/share it.
