I would likely be creating a lot more video game content if I didn't spend as much time on forums as I do now. As a gamer, I love to create content to share with others.
This is honestly a difficult question to answer, because of the forum that I started back in 2003, I discovered I had a passion for creative writing, not only a coping mechanism for unpacking emotional trauma, but also used as a tool for self-improvement. And of course, the sheer joy of providing entertainment for other people! I also wouldn't have discovered many of the anime titles that I've grown to love, the characters, the plots, the crazy chaos... I also wouldn't have learned about several of the various scripting and programming languages if it wasn't for running my own forum.
