Ok, so beyond allowing people to submit articles on things they're passionate about, we could open an invite to people looking to promote something, be it; a new steemit business/project, website, indie game, new album, gofundme project, small business, a fucking movie I don't care.
Obviously we wouldn't just post pure advertisements, rather people could write a background piece, add pictures and make their project look really interesting all while providing a good article for us to publish.
This would open the door to grow our audience well beyond the confines of steemit by utilising other forums and communities to engage with people, while also bringing in lots of submissions.
So how can this make money?? Well by initially offering a free platform to promote stuff people will be incentivised to engage, subsequently growing our audience. Eventually we could charge a fee to advertise on the magazine or even write for a project. Additionally this will gain income from steemit by engaging with people who actually want to properly use this platform, as well as, gain attention from potential delegators by having outside attention (they love mainstream connections and cross-platform utilisation).
Of course we would still post regular articles to grow the account that way, but like any magazine, ads are key to profit. And being a social platform, followers a the key to all other opportunities.
