Tech Crunch has confirmed what AllFacebook noted late yesterday: new functionality on Facebook comments. While the company will probably never roll out the much asked-for Dislike button, what they’re trying is the next best thing. The idea is to be able to vote a comment up or down with little green or red arrows. While that might be an interesting thing on Facebook (or a stupid and distractingly competitive thing), the real story here is Facebook building a robust commenting framework to export to other sites. Why run your own commenting system with all the hassle that goes into it when you can have Facebook run it for you? Then they extend their reach even further into the internet and our lives. See? Everyone wins! Except everyone other than Facebook!
