Why Instagram ? this is the only application currently connects all types of photographers which can show off their skills ... Connectivity - Facebook like
Why not others - Coz others don't have the servers to store the photos you click & share.
So, your another option to share your photos shall be(if you are using instagram to connect other photographers) ... Take photo, Edit using Littlephoto/Vignette/Pixl-o-matic etc., & upload using Instagram
As simple as it is...
