Do you like seeing an empty profile? Without description?
If the answer to these two questions is NO then you should know that the other members of the community don't like it either.
Having a description is giving yourself the chance to stand out and especially to make those who come to you want to know more and meet you.
Of course, this advice applies to your profile in general, we strongly advise you to put an avatar, to be certified, to publish content and to fill in all the information on your profile.
