Two or three years ago, when I had no idea what I was doing with networking at the Game Developers Conference, I was recommended to read this guide to Effective Networking In The Game Industry written by Darius Kazemi. He covers many aspects of networking, and it helped me a ton. I highly recommend it if you’re ever planning on going to GDC.
I sent Darius an e-mail recently to thank him, and wrote about how his blog changed my perspective. He was interested in making the e-mail into a blog post, and now you can check it out on his website!
