Brother Stuck, by his own admission, routinely posts here on JWN during meetings while working the sound!
I've posted here a couple times while running microphones. Between getting to vent in real time about the stupid BS being spouted, and the adrenaline from having to seamlessly switch over to the WT when someone on my aisle gets called on, it makes the meetings slightly more tolerable.
As far as the JW.org frenzy, I'm not sure if it'll help or hurt long-term. I'm leaning towards it hurting the cult, though, simply because it is a tacit approval for JWs to go online. I think the main issue, though, is just the internet in general. If anyone is having doubts, they'll eventually build to the point that they have to express it to someone, somehow. Expressing doubts to elders is an unwritten no-no (even if it's officially encouraged so that you can recieve 'spiritual direction') because you know it'll turn into a whole ordeal. So where is one to go so that they can anonymously express/discuss their issue with the organization? I was in that situation, and that's exactly how I ended up here. I was completely mentally out within 3 days. I think this would play out with or without JW.org.
I will say, I'm a little bummed that they finally started releasing the KM on the site for everyone to get. Getting my KMs off of jwleaks was quite instrumental to my awakening. The unbiased nature of the site with it's "here's the documentation, you make your own assessment" style kept the "bitter appostate" alarm bells from ringing. Then little seeds like "why would someone bother to coin the acronym TTATT if there's nothing wrong with the org?" were planted, and it eventually led me here.
