There is "spending money/mad money, so to speak") to be made here. Even then, it is not immediate nor monthly for the vast majority. It is entirely up to the individual writer, their talent, energy and time invested.
BTW....if you choose to give HP a go, you would be wise to visit the Learning Center, snoop around and get a feel for the community, read hubs written by our members, perhaps comment and ask questions.. People here are happy to help newbies.
BTW, we don't "blog" here.....this is not a site for blogging or bloggers. We are free-lance writers, magazine article writers, Indy authors of novels & books of poetry, How-to's etc. Best of luck to you.
