Ah, it seems you may have misunderstood the intention of my post. It was rather vague so allow me to elaborate.
By 'networking', I do not simply mean 'hand out business cards at corporate events' or 'friend every composer on social media'. To do so in such an industry can be seen as both pretentious and desperate.
However, it is also folly to sell people this rose-tinted version of 'being an artist' or 'being in it for the art'. Talent alone does not suffice in this modern age. Art itself does not put food on the table or keep a roof over your head. It may seem like a nice romantic idea when you are an angsty teenager still living at home but when you have left home and are faced with making your own way in the world, priorities change and bills need to be paid. The truth is that artists get where they are through a holy trinity of talent, business know-how and a good degree of tenacity. Most aspiring artists and composers will be told at least once in their career that they are not good enough. Give it up and get a real job. The difference between those who truly believe in their art and those who do it for the fame/money comes down to those who won't take no for an answer. And this is where networking comes into further play.
(I might also add at this point that the saying 'Do what you love and you'll never work a day in your life' is a dangerous one and one that is frequently shared with this dreamy view of being an artist. It sets up false expectations that can be fatal to the aspiring composer. Its one thing to be inspired but another to be aware of the dangers on our path and how we might best avoid them)
This site itself is a prime example of networking working in tandem with talent and tenacity. Aspiring artists post their work looking for peer feedback. Most will (lets be honest, this could also be read as 'should') take this feedback on with a good deal of humility and go away to hone their craft. With any luck, learning one or two things along the way. So they come back and post again, receiving more feedback and going away once more to tweak their work a little more. This goes on and on, post begat feedback, feedback begat change. Eventually they may submit their work to the OC judges and are either given the thumbs up or told to come back again another day. Once more allowing the circle to begin anew. And remember, this is just one example of networking in action.
You say that artists need to stand out from the crowd and deliver something awesome and unique. But who and how do we decide that? We do through the sharing of information and opinion on social platforms, electronic or otherwise.
Ultimately, it is what happens to work for the individual through their own process of research and a period of trial/error reflection. In other words, don't look to one person for the answer. Find out what works for you through the amalgamation of different views and experiences. There is no magic formula for 'making it'. Furthermore, I might add that teaching is not about giving the answers to a blank slate but rather facilitate the learning process so that answers can be sought out by the students on their own merit. I would prefer my students to be 'infuriated' with my answers, and go away to try and prove me wrong. This itself gives them the drive to find out the answers for themselves and ultimately come to their own conclusions. This, I'm sure you would agree, allows for a more holistic style of learning that benefits all those involved.
