With the inclusion of Doctype into the discussion, the suggestion that we simply ignore the tags came to the forefront. This has me wondering if users of stackexchange would need to explicitly ignore every new item each day simply to keep their list of visible items clean and un-cluttered.
Could we have an opt-in option for cleared-tags? Meaning, you only show me what I explicitly state I want to see until I decide otherwise. That way, users don't have to login, ignore all the new tags for the day, and then get back to familiar browsing. Day 2, repeat, etc.
Basically, every tag is uninteresting if it's not in the interesting list. I don't mean to suggest this as default behavior of SO. This would be a preference for users. And opt-in service.
