The surest rule in this industry is that networking is everything. No one can produce a full length feature film or a triple-A game title on their own. Often times, the people you worked with on one project, or went to school with, are likely to be the ones who help you get a job 2 or 3 or even 10 years down the road. Many studios, especially in this current economy, only keep a small group of core artists and bid out the rest of the work to freelancers and other smaller studios. Even the biggest names in the industry spend a good chunk of their time freelancing. So for those of us looking for work, it's really a bad idea to shun social media - it's a powerful tool in today's market, so by not using it to your advantage, you're really only hurting yourself. It's basically free advertising for your talent.
