This is my concern as well. The idea here seems to be that the thing that offends the least must be fact.

This behaves very differently for falsifiable vs. non-falsifiable information, but the end result is not something in which I'd place much stock either way.

Edit: to be clear, from Twitter's perspective, this is excellent, i.e. this is precisely what a revenue-motivated entity would want. It's the rest of the world that I'm concerned about.
