What I'm not understanding, and the Primer didn't really clarify for me, is how to "clear" my feed page to see new content. On Reddit I can set it up so that once a post is up- or downvoted it will disappear from my front page once the page is refreshed. How does that work here? Is the only way to remove a post from appearing in my feed to hide it? Is there any way to "upvote" a post without me sharing it with whoever is following me? Because while there are many posts I may like and think are positive contributions, I won't want to share all of them with my followers.
The autohide after a visit is interesting. It might be worthy of an settings option. That said, we are keen on supporting a slower pace of consumption. As for "voting without sharing", it's intentional that everything is shared or not. The consideration that the consequence of sharing requires is exactly what we want to encourage. If it's not worth sharing, then it simply is not. Interestingly, we frequently have posts that have very many comments and few shares; but, eventually they are shared for the discussion that occurred, rather than the content of the post itself.
To be honest, I think the "hide" for each post on the feed is sufficient. Implementing an autohide feature, even if it's something you have to turn on, could result in people having difficulty finding posts they want to go back to, to converse on.
From how I understand it:
You shouldn't think of voting as sharing with your followers – like Twitter. Voting simply means "I found this interesting", by definition anything you find interesting will also likely be interesting to those who follow you; and if it isn't interesting to them, they won't be following you. So don't worry about what your followers might think of what you're sharing; if the system works they'll find a post as interesting as you did.
