I have been offered 2 contract positions without linked-in profiles So my answer it is not necessary. I mostly use linked-in to post articles of interest to me in the various groups as a way to promote open source code repos from authors who publish their software as well as their findings It is my hope that by posting such articles/work I will encourage more authors to publish their code so we can all grow together
