I was thinking creating one that is about world events/places.
So something like this:
Five places in the world.
Two events.
A main theme of the magazine such as industry with two recent industrial events.
But, just from far away, this seems pretty ambitious. Were would the stories on sciences and emerging technology come from? Are you going to write them?
Anyway...I've no experience or interest in starting my own magazine. I would think that would be a new full time job and I already have several.
