I'm not trying to rain on the parade here but I don't think those stats tells us the whole picture. You can easily count the threads where there is a real discussion going on. Most posts in international boards (Altcoin, Bitcoin, Trading, News) are just copied articles or just rephrased from the articles. Those posters don't even interact with the community. They just grab the image from the article, spin some words, post, and that's it. Repeat the same thing on the next topic.
Aside from that, there are also plenty of spam mega threads where users just post to meet weekly quota.
