Good luck getting 200 'good' submissions a week. From my own experience, you'd be lucky to get that many from 'local' contributors in 12 months....
And how are you going to pay for that '...
good editing and excellent content, requiring contributors and editors with credibility from the start.'?
That doesn't come cheap.
Anyway...bring it on. I'd love to see a new publication enter the local astro scene. I'll keep an eye out for it, eh?
