it resembles Facebook friending.
In many ways that addresses my own discontent. Our intentions are far less important than the effect.
Perhaps the intent should be made more clear, then. Instead of saying "follow mk," you should say "subcribe to mk's content."
If I could only follow tags, I may as well be subcribing to a sub-Reddit. And I have no desire to do that again. So, I don't follow tags, and, honestly, I think the ability to do so only confuses new users, who will decide Hubski is just like Reddit, but with updots instead of upvotes.
Just try to make it clear how the site was designed to be used, and only add features that enhance that use.
