Somewhat off topic. But why does this community rack up so many notifications so that when viewed in the "All Communities" page it can have 69 new since yesterday? And yet the last new post was yesterday. What do those little numbers in red on that page actually mean? Same for the numbers in the sidebar here where Discussion is marked as 52 new.

If it's counting new +1s that's uninteresting. But also who or what is it that likes adding so many +1s to articles in this group? I guess it's some kind of spam thing, but what's the benefit to them?

Whatever. I'd rather G+ only counted new posts and comments in those "New" numbers not +1s
