I have enjoyed Steepshot a lot. it has made Steemit more image focused, and I like how it's integrated. Though I am hoping they put in the Markup language into the posts (as they reflect into Steemit, but not there) and that follows on Steemit/Steepshot will automatically reflect. It seems not all pictures/photos from your Steemit blog will work on Steepshot. I think it's a great service, slower than Instagram, but also good (with the Android app and all).
