No disrespect taken! I rely on the Coppermind WoB archive to stay on top of the most relevant Cosmere insights like I'm sure you do as well.
The Coppermind doesn't capture Brandon's commentary on his writing method, memes, or other less-plot relevant content. I'm sure that isn't everyone's interest, but for others, they could be interested in that content without having to wade through all the other Reddit fluff.
