Hello, I think the package descriptions are a very important product of this project. They're going to be one of the first things people see when they use Debian, and their quality directly reflects on the quality of Debian. I've been putting in some random efforts here and there to comment on new package descriptions, but I finally sat down and committed my thoughts on description writing in a semi-coherent form:
