There is a new app called Glass. Glass is trying to recapture the essence of Instagram before Instagram’s sellout to Facebook and it’s pivot to video.
At the moment Glass is focused on building it’s own photographer community and is €30 per year. Steep for an app with limited functions other than hosting pictures. VSCO is a similar photo only platform and for the same subscription gives you great photo editing tools.
You can share by link only to individual pictures as you can see. App could be viewed as a ponsi scheme as people have to join to see all your photos.
