Good context! I appreciate the thoughts.
I was honestly thinking about it from a data perspective.
Imagine if we had both an Upvote and a Share button, for example. The upvote has no mojo with it. It's just a way to say, Yeah! or Right on! or Thanks for the conversation!
While the Share button would be "hey everyone, this is super fascinating, and everyone that follows these tags, this post, or this person, should read it!"
A couple weeks ago we had an interesting sub-thread in another conversation about what the hubwheel is "for", and I had the distinct feeling that people agreed it was not an Upvote, it was a Share.
Judging from the amount of butthurt on this post, I'd say people have changed their minds!! :-)
