I think perhaps an anti-JW.org would be great. Not necessarily the meat and potatoes content about 607 and 1914 nobody in the organization would ever understand or reads, but simple articles, if well written, targeted at specific audiences (young people, people thinking about joining and actual members).
The one thing the JW does well is have catchy phrases and seemingly deep questions that pull you in, then they use deceptive tricks (1 truth and a half truth) to make people think they have good answers. So if you take the same approach but use actual correct reasoning, you can point out logical inconsistency.
I’m not necessarily a good writer, but I can editorialize and research pretty well, I’d be willing to help out, but I have a real life now, so I can’t dedicate hours per day to this.
