How many JW read their magazines? Read the Bible daily? Participate at the meetings? Pioneer? How many do recognize 'new light' when they read it? (Usually the WT needs a footnote to indicate: this is new light.) How many are really able to lead a Bible study? Etc.
Really, most JW aren't very jolly about their religion: they're followers, not more. Maybe just 10% is really active and happy about it. The rest is mentally inactive.
So, I am not suprised that most jdubs aren't very exited with tv.jw.org.
