It looks like you’re part of one of our experiments. The logged-in mobile web experience is currently unavailable for a portion of users. To access the site you can log on via desktop, the mobile apps, or wait for the experiment to conclude.

Jeez. The speed at which I’ve gone from “man it sucks that Apollo is shutting down but I still really enjoy Reddit and will suffer the first-party client” to “wow, Reddit is really trying to destroy their service and it’s probably best I don’t invest any more time there” is insane… going to draft up some thoughts and a probable farewell message for my frequented subs and followers there. End of an era.
