That's the point, though. Having it curated and written by experts puts them in control of what direction you go. Realistically, I could click through the radiation article on wikipedia, and may be exposed to what I need to know, but I also could just wander down a rabbit hole of useless information.

That's the entire point. I'm not the expert. Nor am I able to even understand the basics of which direction to read/learn - that's what the expert curators are for.
