Its really nice to just sit down and watch "whatever is on" (even though I could switch over to the main library and watch any episode I want).
Sometimes I just want a 0-effort/0-decision background noise while I work on something else or browse on my phone.
I quite like it. Unfortunately, the app's been a bit buggy - not always picking up the stream at the "current time" and sometimes navigation gets wonky. But it was a good test run and that, along with your post, has convinced me to give Ersatz (or something like it) a try.
