FWIW, the moderators have released the traffic statistics for the Reddit ExJW Subreddit
Web statistics are not generally an exact science - the 'best' indication is normally the 'unique' visitor number - although one person may be using more than one device to access the website (ie using desktop and mobile), but also more than one person may being using the same device (ie a shared home desktop).
On a forum-style website,
the number of 'page views' is a bit pointless as it will normally
always be much, much higher than a non-forum-style website - but it can
give a general idea on how engaged visitors are (how many topics/threads
they are reading)
