Over the past few months, Twitter CEO Jack Dorsey has been adamant that one of his goals is to " increase the health of public conversation " on the site. Because it's no secret that, as great as Twitter is at connecting you with people across the world, it's also great at connecting you with bots, trolls and spam. Unsurprisingly, Twitter wants to change that. And it's hoping to find a solution by publicly testing new conversation features , through an experimental program that users can apply to participate in . This launched last week as an app called Twttr , which I've been using as my main tool for reading and writing tweets for the past week.
