Since the days of USENET there have been flamers and trolls.

I believe they are tackling this problem from the beginning and making it a big part of the design of the platform:

  1. Comments require the author to approve for being public. Here most of the trolls are avoided because who would approve a troll comment.
  2. Responses need to be recommended by the author or someone you are following in order to show up by default (else they are buried under a “Show more responses” button).
  3. Posts that are not recommended by your network don’t get visibility.

All these work in favour of good content and against trolls, and helps to shape the platform in a better way than others (imho).

Definitely worth emulating where possible.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
