I think I would be well suited to help improve the glossary. I don't know the terminology, so I always notice it when I see it. I look the words up as I see them, but obviously I am not qualified or well enough informed to write the definitions. I would be happy to make a list of the words that haven't been defined yet and add them to a post of words requiring definition. Should I do this?
I suggest that you go ahead and start a community-wikified list of requested additions to the Glossary, either as a re-write of this question post, as an answer to it, or as a new question post. Then, ask Glossary editors to delete or strike-out entries on your list as they add them to the Glossary.
