I realized that VR, as a medium, is uniquely tuned to people, and I think you would have a great blog if you focused on just that: people.
What are some ideas for how can VR help people? Can it help people fight depression? Can it be used for physical or emotional therapy? Can it help them safely build skills that could improve their lives?
On that last one, I am reading a book about ship handling. It was a Christmas present because I will never be a captain in my life. But ship handling would work so well in VR. Even the commands are so standardized that players could give voice commands, a real bridge.
How many Make-a-Wish kids or others could have a wonderful time doing that? And that isn't even considering the idea of extending that game into space with Star Trek USS Enterprise or Star Wars Star Destroyers.
Your site could be the nexus of those great ideas. You could even have guest posts. I'd write one.
Anyway, sorry for the novel. VR has helped me feel better than I have in a long time.
