This week, Sony released a new platform for engaging with the social features on PS4. Called My PlayStation, it allows you to view, manage, and message your friends and see your Trophies.

My PlayStation is now accessible on PC, phones, and tablets through a web browser, and it essentially looks like a streamlined version of your PS4 profile. From it, you can access your friends list, message your friends, and accept requests. You can also edit your profile and view the Trophies you've earned. You can also check whether or not your friends are online and what they're playing.
