Yesterday I went swimming and thought about tags the entire time. Don't think there aren't times that I click on the tag field and think: "WTF should I tag this as?!" Some creative tension is a good thing. Too much is a bad thing. I admit it is debatable. To me, tags represent more than the name implies. They have editorial, subscription, grouping, creative, and temporal (i.e. trending) components, and I'm thinking on these. If tags do change, they need to bring an improvement measured in terms of all these components, what users want to do with them, without breaking, or encouraging gaming of them. And, they also have to be weighted against current content management. Following a tag means that you get a post from anyone that used that tag (barring ignored users). It's a huge effect. Yeah, we can have that tag thread soon. But I need a swim or two more first.
