Firstly, I disagree that the Facebook experience is that bad. The content of my social graph is pretty lame these days, but the website itself is pretty usable, and some features (okay, maybe just Messenger) are top tier. But secondly and more importantly, it seems bizarre to be amazed that a useful developer tool could be used to make a website that you don’t enjoy. Of course any decent developer tool could be used to make products that you enjoy as well as products you don’t enjoy.
