It’s not worth hitting the front page of blog as the information is usually unreliable. Active Users is a case in point. When was that data cleansed? I would venture an answer of never! There are always figures shown as active users who are not active users, people who have openly moved elsewhere, or people who no longer blog.
I have no idea what turgid technology is in use, but if the front page programming can’t be accurate, it would be better to re-design it or not have it at all. It makes you think that BCUK does not have very many active users.
