'Needs no introduction' - flattering, or just bloody lazy?

[oursin]

While it may be gratifying to one's ego when one's session is introduced during a conference as '[X] needs no introduction', is this not a bit of a cop-out on the part of whoever's chairing?

At one very small conference recently where I had this sort of intro, one of the postgrads attending asked me later who I was (as I was fairly outwith their particular disciplinary speciality, and there was no particular reason why they should have known Who I Was - I am not an academic superstar).

This also happened at another recent conference, and while this was also quite small and associated with my home institution, I wouldn't have expected my name and work necessarily to have been known to everybody there.

Maybe these days, chairs expect anyone who doesn't know to be checking on their iPhones to find out?
