I especially like certain jump thoughts to not be attached anywhere. They just don't need to be in some cases; it's like sidebar note. But...the more you have, the less valuable the Parentless report becomes. There my "parentless" parent solution comes in.
Quote: I've gone through a slow process of loosening my hierarchical system over the years of using TheBrain, drifting towards information centers that make sense to me and the way I use the information
That's one of the things I like from A-Z. Everything has a logical place without needing to overthink it. Don't know where it goes? Put it under the right letter.
As for using information, I agree that hierarchical just isn't so important; associations are. Sure, drill down is valuable up to a point but we have search and the connections. For me it's important, like Metta says, to make those connections. "Sitemaps should be like this" → hey, there is a module for Wordpress that makes sitemaps, etc.
So, back to parentless thoughts; how do you deal with those in reporting?
