As interesting as the like feature is, I don't get a lot of information from it, since everyone uses it in different ways. Some of my readers like every chapter, which... okay, yeah, it can be fun to wake up to see that a new reader found it and liked every chapter overnight, but it doesn't sway my decision with what chapters to write when everything gets a like! Then I have readers that do like the particular paths that have kinks and such that they enjoy.
But I also have situations like... I wrote a path that was pretty dark for my story, there were like 6-7 chapters that progressed before resolving with another chapter. Those middle chapters get very few, if any, likes. But the resolution got a lot of likes! But I wouldn't have known if it weren't for comments and messages saying that readers worried for the safety of one of my characters, and when she was okay in the end, they were relieved. Which... aww, that's sweet! I think that's a big compliment for the character's development. But then I wouldn't have really understood what was happening without those comments, I just would've thought everyone hated those chapters because of how I wrote, but it was more that the ordeal was necessary to set up that well-liked resolution. (...maybe they also do actually hate the chapters too. I can't really be sure. But they definitely read them to understand the resolution!)
Anyway, deciphering likes for what I'm going to do with branches is definitely not as easy as comments, but comments are so much rarer to come by. If I wanted more useful one-click feedback, what would maybe be interesting is a 'vote', where readers could cast maybe one, or just a handful, of votes, on what path they'd like to see more of in a story. But just about any decisions beyond just what I felt like that day for adding new content come from comments.
