Have you tried using the site-wide search? Just type 'triple negative' or other key words into the search field (top of the page, just above the main navigation where it says 'start your search here').  When the results come back, look at the right of each listing and you'll see which are website pages, and which are blog posts.  If you click through to the blog posts, you'll find others who have posted on the topic, and you can then send a personal message if you would like to make contact.

Hope that helps.
