They added many new people over the last few years. The last time I got the guide several years ago I looked over the advisor list and thought to myself, who are all these people? I still don't know who they are. I'd love to know the criteria they use to pick advisors.
They do add new people. I don't have a current guide but just picked up my 2020-2021 edition, and quickly counted at least a dozen Boardies. Foolkiller was an advisor briefly, I think of him as an excellent choice. After the folks from the Boards, there's a lot of folks that I don't know personally but I know who they are or I've dealt with them before, and then there's also some I'm unfamiliar with. Then there's some folks whose presence leaves me scratching my head, guys who've been banned from the Boards, guys who are a known bad quantity in my book.
