No idea on @Mittineague thoughts, but I’ve been living with it for 14 days and the noise here isn’t bad. If it were on a site that heavily uses Wiki topics, I might change my mind on it, but then again, I might just choose not to watch everything.
I really do not see a big deal with this as the first iteration of the feature, it works, it does draw my attention to wiki topics that are changed leaving it to me to decide if I care about the change or not.
