I am afraid that given the lack of similar words for "gravitas", I would have to write a fairly boring post, chock-full of the word "gravitas", thus alienating me from those who might, from time to time, find this blog enlightening or amusing.
I esteem myself well enough not to do that. While it might not have a deleterious effect on you, as a reader, I myself would find it egregious.
