Snapchat is more than ephemeral with Memories. Pokemon Go rules the world. And we pick up on Walt Mossberg's discussion of our fragmented messaging environment. Gini Dietrich, Martin Waxman and Joseph Thornley tackle these topics and more in this week’s Inside PR podcast. #IPRMustKnow Snapchat Memories for when ephemeral isn't enough Hard on the heels of news that Snapchat has surpassed Twitter in daily users, we say Snapchat switch from its ephemeral-always model to provide users with the ability to save their Snaps using a new feature, Snapchat Memories. Memories lets you save current and previous Snaps and then use them for future stories. So, now you never need to worry people missing that embarrassing photo of your best friend that you sent out 25 hours ago. You can reach into Memories, add the photo to a new story, and start the cycle all over again. Pokemon Go Goes Like virtually everyone else this past week, we have been entranced by Pokemon Go.

Pain the butt? We riff on a theme recently explored by Walt Mossberg in a blog post, The Tyranny of Messaging and Notifications, and on his podcast, Ctrl-Walt-Delete.
