I have a feature suggestion for qanon.pub.

It would be convenient of the page title (presently "Q") showed the current number of posts, because this would make it easy to tell if there's NEW Q!!! without switching to that window/tab.

I believe this can be done by, at the end of function checkForNewPosts(), adding this one line of code:

document.title="Q ["+posts.length+"]";
