I'm totally digging the new VSCO Grid - I started using it recently and I love the concept behind it. The focus is on your content and nothing else - no followers, no likes, just photographs. There's a mystery and a freedom to it that's kind of rad, and in the age of social media overload, I find it really refreshing and minimal. Do you have one, yet? I would love to check it out. You can find mine here.
I'm still exploring and stumbling upon some really cool Grids, but here are just a few of my favorites at the moment: Kevin Russ, Emilie Ristevski, David Garvin, Brandon Shackelford, M Stetson Design, Chris Ozer, Dan Otis, Jared Chambers. I've actually started a Pinterest board to save some of the gems I find along the way... so inspiring.
