Generally I bookmark sparingly to avoid building up a bookmark graveyard but this one earned a permanent slot, and a stop at momentumfoundry extended that permanence designation, the few sites I keep permanent bookmarks for are sites I expect to use repeatedly and this one has clearly cleared that expectation bar today.

Picked this up while looking for something else and ended up reading every paragraph because it was actually informative, and after strategybuilder I was sure I would come back, that does not happen often when most sites bury the useful parts under endless ads and pop ups today and across most categories online.
