Add President Barack Obama to Facebook’s 1 billion-plus users.

The POTUS has joined the most popular social network on the planet, a surprising development as one would think he’d have gotten a page up at some point during his seven years in office … or before.

In his first post, Obama write he hopes users will “think of this as a place where we can have real conversations about the most important issues facing our country – a place where you can hear directly from me, and share your own thoughts and stories. ”

While we’re sure the president will talk about topics like health care and the economy, he also writes his page will feature “some just-for-fun stuff, too.”

The first POTUS post

In addition to serving as an introduction to his page, President Obama’s first post includes a description and video of him walking through his backyard – aka the literal national park behind the White House.

He casually strolls across the lawn, talking about a fox and a hawk named Lincoln. He segues into a message about preserving this park, all US national parks and the planet as a whole by acting on climate change.

Obama talks about US leadership to combat climate change, the upcoming meetings in Paris, and ends with a call to action to viewers to get passionate about and start acting on the issue, including on the very platform he just joined .

At the time of writing, the presidents video had been viewed 78,000 times with over 5,050 likes (Update: Views are now up to 128,000 and likes topping 9,328).

Sheryl Sandberg, COO of Facebook, is the top comment, writing: “Welcome to Facebook, President Obama! Excited for you to have your very own Page – and looking forward to the conversation (and the just-for -fun stuff). “
