I have not actively used Reddit in over a year and am better for it. Their design is one of the most hostile I have seen in a website. I wish it was an area that allowed for competition because someone needs to give Reddit's head a shake.
The catch is that both of those usage modes are pretty much at the mercy of Reddit Inc., which could decide to "deprecate" them at any time they see fit. And given that Reddit Inc. seems to be planning an IPO, I imagine that those will both be on the chopping block sooner rather than later.
I didn't want or appreciate some of those features anyway. Old Reddit with RES pretty much feels feature-complete to me. In some sense it's also refreshing to use a popular social media UI that isn't going through constant redesigns and tweaks.
