Do you have any idea how many subscribers you would have to have and how much writing you would have to do to earn a living?
If all 208 of my RSS subscribers were to sign up for this to pay me a penny per post (highly unlikely), and I posted every day (also highly unlikely), I'd make about $759/year
I think only a small percentage (if any) would actually sign up for this, therefore, I'd need 1000's of readers and would have to write all day to scratch out a living that would still be below the poverty level in most parts of the US.
Just to cover the cost of the rent on my apartment (which is pretty cheap for where I live), I'd need 3140 regular readers willing to sign up for this AND I'd have to post every day.
But with my current readership, the small percentage of readers that might sign up for this would likely be 1 (or less), translating to $3.65 a year, at most (with a post a day), but with the way I post, more like $0.50/year.
