I am going to guess that the percentage of these comments on this page is going to vary greatly from person to person (no big observation there), but in my case, I'd be surprised if it's any more than 10-15% of the total, which is pretty significant, but meaning the other 85-90% is coming from other posts, which I think is pretty good. There's a bunch of engagers here, so it's only natural we're going to do that. :)
