There is more to this than just Reddit. For one thing, there's a different approach to identity, and for another there's summaries and whatnot that get automatically pulled. And, for all we know, other additions that he hasn't shared yet. Plus, reinventing Reddit is not necessarily a bad thing. For example, the site you are using right now.
Also, your comment is itself a bit Eternal Septemberish -- you know, the belittling, and the intentional disregarding of differences between Monocle and Reddit. Not sure if that's meant as implicit metacommentary or if you aren't actually aware that you are contributing negatively.
