The current richest human being in the world, Bill Gates, has joined popular social media platform, Instagram.

Instagram just got a new follower: Microsoft cofounder Bill Gates.

The richest person in the world made his debut on the photo-sharing platform on Friday morning under the username “thisisbillgates” (“billgates” was already taken). His first Instagram post is a slideshow of three photos from Tanzania.

He captioned his photos thus:

“Hello from Tanzania, Instagram! I just had a great lunch with some amazing kids at Kicheba Primary School in Muheza and met Upendo Mwingira, a remarkable physician who has dedicated her career to fighting neglected tropical diseases. Melinda and I have been coming to Tanzania for many years now. I always love seeing how much progress the country has made to improve health and provide opportunity. Plus, the scenery is stunning. Whenever I travel to places like this, I wish others could come along and meet the people I get to meet. I have no doubt it would leave them as optimistic as I am about progress happening around the world. I’ll be sharing photos from my adventures here on Instagram, and I hope you’ll follow along.”

This comes just three weeks after another tech billionaire made his Instagram entrance – Amazon founder and CEO Jeff Bezos. For a brief morning on July 27, Bezos usurped Gates’ reign as the richest person in the world on the FORBES’ Real Time Billionaires List. Gates has taken the No. 1 spot on the FORBES annual Billionaires List for 19 or the past 23 years.

While Bezos’ first post included drone aerial footage to promote his rocket factory, Gates has taken a more subdued tone for his debut by sharing his optimism for progress in the developing world.
