Twitter CEO admits 'we suck at dealing with trolls,' vows to fix it

I'm all about getting rid of trolls. However, I'm worried that various groups will use words like 'troll' to silence opposing opinions. It already happens on many Internet discussion forums.

Gamergate is a great example of this. I saw terrible messages and actions from both sides, but it really depends on personal opinion whether the opposing message will be considered a 'troll'.

Isn't the the issue troll had more to do with gawker making the coca-cola bot quoting mein-kampf ?
