this will never work. the problem is people will add whatever semantics get them more sales. If tagging a site about dogs as "cats" gets 5% more visitors, even if they're pissed off it will still translate into more sales. Further, getting everyone to agree on semantics is impossible. You can already see this in action on soundcloud. Search for any music category and you won't be 5 songs in until you find a song that doesn't fit the category. Whether that's because the creator legitimately thought the tag belonged or if they just thought it would get them more listens it doesn't really matter. What matters is the tags become useless I see this on many sites. Stack Overflow uses tags to add semantics. It only kind of works because of a vast army of volunteers fixing the tags.
