A thing I miss already

there's no "like"/"+1"/some other quick and dirty way to give feedback.

Comments

probably less, because a "good post" comment requires more effort than clicking a button and people coming from Twitter or Tumblr will start with the attitude that "you don't comment unless you have something worth saying". Alas.

That makes sense. If the options are between 1) say nothing unless you have something well-thought and constructive to say, or 2) say whatever you’re thinking to engage with others, even if it’s only a few words, most people will go with option 1.
Against all my internal programming, I might take a step out of my comfort zone and go with option 2.
