Yeah, this definitely is a way to break the filter bubble.

But thinking about it a bit more, it might be one of the worst ways to do so.

For example, assuming roughly that both favorites and retweets represent general agreement, using those mechanisms to surface new tweets to people makes sense. If someone you follow (and presumably respect) quote retweets someone you don't follow with "Yes this!" or something similar, then you're already primed to agree with the person you follow.

But, often at least, replying and not faving/retweeting could very well bais for DISagreement. Now instead you're going to see someone you follow and respect arguing about something, and you're primed to agree with them, and potentially pile on to the original tweet author even though you might not have cared about the topic a minute ago.

Twitter ALREADY has a way to signal that you want all your followers to see a tweet you saw: retweet. And even showing your followers things you favorited at least means they'll see things you probably like. But it seems there's at least a reasonable argument that showing your replies to your followers is setting up a situation where pile-ons to the original tweet are likely.
