I was thinking of asking this.
I have experimented with changing meta descriptions on selected pages of my encyclopaedia type site, and it made no difference. I think most people scan the titles and rarely read the meta descriptions.
A lot of my competitors do have something in the titles like "explained" or "defined", so I have been wondering about what I should try there.
