But there's another piece to Darwinian selection: It's not just reproduction of the fittest, but reproduction with variations. Sometimes, that's where the real value lies. If you look at biological ecosystems, ultimately, it's where all the value lies. That's where you get new ideas, by riffing off of other ideas, modifying them, and mashing them up. Making this harder is, well, bad.
It's not like they haven't thought of this. @ev does give some hints of future possibilities:
eep in mind, there's nothing stopping you from simply quoting another tweet if that's what you want to do. Also, old-school retweets are still allowed, as well. We had to prioritize some use cases over others in this release. But just as Twitter didn't have this functionality at all before, people can still work around and do whatever they want. This just gives another option.This ignores the change in affordances with NewRetweet. Tools support ClassicRetweet today; I fear they're gearing up to switch over to the shiny NewRetweet, putting a barrier in front of users who want to propagate-with-comments. It'd going to be even more confusing because they're keeping the name Retweet but taking a way an important piece of functionality. We can't even talk about the differences without inventing new vocabulary
