I haven't started following individual articles yet but have noticed changes to some of the articles I reference frequently. Instead of going through and following various articles individually, I'd enjoy the ability to Follow All. As an Aha! SME, I'd like to stay up to speed on any changes to the content in the Support section. Concurrently, being able to Unfollow some articles that I don't end needing to track would help reduce my notifications and improve an already great experience.
