At least initially, it won't have any user-generated-content as in comments (the articles will have a submission system). It may be something that I add eventually but it inevitably ends up being something that needs to be moderated to protect against spammer and trolls. And the intention is that if someone wants to comment on a video for instance, they can do it on YouTube where all the other comments will be.
Interesting you mention the exist stories, as we did a whole series a while back that I think were very powerful in removing the "apostates are out to get us" stigma and to show that we're real people, just like a JW who may be reading.
