Instagram???

Am I the only person that does instagram out of a sense of duty? I know I'm a bit old fashioned  but  I just don't like interacting with phones for photography. The screens are too small. Instagram is a mobile based app but all my proper photography gets done on a PC. That's where I store, process and interact. For me Instagram is an afterthought, I don't consider it  my serious outlet. And yet it is very popular, especially with the high profile photographers. I just don't know how to use it effectively. I cant help but think I am missing out by not utilising it well enough, but it's so hard to know where to start. I have essentially just been posting into the void, hoping to be found, but tbh that's also true of twitter. I suppose I am just not good at this networking stuff.
