In my limited experience with the site, tags hadn't affected much of what I viewed. This is largely due to the unstructured taxonomy of tagging - it's all ad-hoc, and the community must decide what is and isn't a relevant tag. Your #politics is my #mudslinging, my #finance is your #thecrumblingcapitalistkakistocracy. That said, I await @kleinbl00 on this thread with baited breath, as I understand he was staunchly in favor of tags and am interested to hear his arguments. I only describe, above, my limited interaction with the site and its navigation, as well as speculation on what could and couldn't happen with the tagging structure as such. Really like the 'unshared' button, though. Nice feature. 'New' may not be as much of a need in light of the intense focus on user-based sharing/following, as 'unshared' is sort of a de facto 'unfollowed'.
