Quite a disciplined policy by the stewards of the website. How does the enforcement work against say, overtagging?
Also this:
> Inactive tags can no longer be used on new stories.
Roughly 100 tags on the page. I see "news" and "ipv6" marked as no longer active. I'm guessing that "inactive" implies dropping from SQL indexes as an economy measure, while retaining unmodified in the original post's metadata.
Tags are used as negative signal, rather than positive (as in, you filter out tags you don't like, rather than taking the ones you do), so overtagging would kill the submission, and missing tags will be added by others via suggestions (which automatically add the tag after some threshold amount of suggestions).
