Well, what do you want to bet that "wah wah my Tumblr-style tag jokes rely on order-of-user-entry preservation" as an invariant makes it Harder to solve "staff are finally trying to improve things re: searchability and tag synonym proliferation"
Obviously I'm biased, in not caring, by my outlier belief that Not Every Text Entry Box Is Inherently A Medium For Moar Recycled Tumblr Jokes, that the CW functionality is actually for CWs, that tags are for tagging, etc.
