Like the topic says, podcasts, and especially audio interviews, should have the audio icon overlay displayed on the front page. This happens on the top bar, but once it goes down to grid/list view, it disappears. This makes it impossible to tell at a glance if a news story is actually a news story or not. For podcasts you can tell from the name of the post, but when you get an interview dumptruck post that looks like a news post, there's no quick way to tell that this is something that needs to be played, rather than read, other than opening it up.
It's really quick and elegant to tell the difference with videos, and with audio while it's still in the top bar, but not once it reaches the list. That seems like it's almost a bug, maybe?
