Okay, I’ll be blunt: I’m a Linux guy. I know, shocker. I’ve recently moved to an awesome new job and part of that role will be an area of developer advocacy which will require me to go to meetups and tech conferences from time to time, and talk about how freakin’ awesome my new employer is. And they are, srsly. You should sign up and use it if you’re thinking about building a news/activity feed/timeline in your app.
