Three years ago today, Instagram launched to the world. Since then, we’ve seen people all around the globe join Instagram to share their lives through photos and videos.

This year, the community experienced a number of important moments. We surpassed 150 million people who use Instagram every month, saw the first InstaMeet in Russia and introduced a new medium: video. We’re humbled and excited to watch the Instagram community continue to grow and thrive.

This weekend’s tag was #WHPnotquitea, which asked participants to take photos or videos in the style of their favorite Instagrammers. Can you guess who inspired them? Visit their profiles to see their captions and find out!

Every Monday we feature some of our favorite submissions from the project, but be sure to check out the rest here.
