I can't comment on why it resonates so well with people, but I noticed that the same Kickstarter was posted earlier today using the original OP title "Omni: Move Naturally in Your Favorite Game" and it received hardly any attention.
Yea that title is pretty bad. "Move naturally in your favorite game" could mean any one of millions of things, when the most important aspect of it is that it goes naturally with an Oculus Rift.
