I don't do enough with them. Share them on instagram/flickr and not much else.
I really need to print some of mine and get some nice frames.

On-line attention is fleeting - in this digital age there's so much available, and you have to become your own editor as never before in terms of what you look at and for how long.
Off-line - if you have an exhibition, it only lasts a month or two. If you make a book, how often might the owner of a copy take it down and look at it?
Photography can have a private purpose - as a creative endeavour, and a way of marking who you think you are. That's valid enough.
Photography can have a family purpose - which is a bit more sociable than the above.
But I could say that if you spend thousands of pounds on equipment for either of the above, then in that department you might be a bit of a w****r.
Photography can have a public / social purpose. Which might function briefly, or come to be marked down in history as significant. In that context, what you might spend is irrelevant.
There's no doubt that it can be a communicative medium. How it communicates, despite the content, is about who's making it and who's looking. Culture has various departments. Crossover can be hard between some of them.
But always ask why. What's it for? Who's it for? Purpose is a key to cultural / human value.
