All writers who want to actually make money need a platform. Writers also need the publishing path that is best for their works and their personalities. I am just as supportive of NYC as self-publishing (though I have frustrations with both).
For me? I write social media books. My publishing path was chosen for me. With a lead-time of a YEAR in NYC? My new book wouldn’t have been out until it was obsolete. For the rest of you. Vive la Revolution! Now you have options. It is no longer a One-Size-Fits-All World.
