The company posted a thank you note on its blog earlier today...
As you’ve captured and shared the moments happening around you, you’ve formed incredibly varied and diverse communities. Whether you’re an illustrator, a sneakerhead or an astronaut on the International Space Station, every photo and video you share helps bring people closer to friends and interests, broadens perspectives and inspires a sense of wonder. You’ve made Instagram a place where the everyday and the epic are always within reach.
Thank you for your creativity, your openness and your passion for sharing your worlds with one another. We can’t wait to see what you create next.
You can download Instagram from the App Store for free.
