As interesting as this blog post was, I don't think it really proves that there is a growing insurrection in the borg.
To give an honest opinion, It sounds like someone pretending to be an active, yet doubtful JW and is expounding on said doubts with the goal of getting "real" JW's to 'discuss' his valid, but apostate leaning doubts.
I wouldn't be suprised if he's a JWN poster.
