I'm starting a new blogging platform soon, where members will be able to publish videos,photos,audios, and text with a free(or unlimited) blog(s) from my platform. My question is, how could I monetize a blogging platform? And how do I effectively promote a blogging platform?
I'd monetize it with AdSense the way Squidoo.com does. Of course the ads will have to look attractive/tasteful on your members' pages.
