Like it or not, Instagram is the strongest platform for photo sharing at this point since 500px never really took off and Flickr is a raging dumpster fire that refuses to go out. I have 2 Instagram accounts that are basically the last vestiges of my social media presence: one for street photography which is a longstanding hobby of mine, and one for more social-media-y stuff and portraits of friends. Instagram, for better or worse (most definitely worse), is the best way to share these photos with a wider audience whether they're selfies or meticulously-edited photos which would otherwise just sit on a harddrive.
