I posed the question if, not said they are feeling that way. 😉

But i think it boils down to a lot of facts and I for example do the same with my speaking appearances – I know a lot about many things but am not that guru in one special thing.

But I do feel comfortable for many reasons (main reason: I am done when I go on the conference) with my pre conference podcasts. I would assume there are more ways than just speaking on such events to get peoples attention. 🙂
