Am really having a new experience. Thanks so much. I discovered that in yalls.org I really need to make some payment before I could read an article. It's a nice way to earn, do I need to make payments to publish an article for people to read?
Yes and yes. It appears to be a pay-to-view site where even the content writers have to pay to publish their articles. It's a zero-sum game between readers and authors i.e. some make a net loss of money and others a net gain.
Could you imagine how small the internet's userbase would be if all pages on the web had to be paid for to be posted? Writers hate paying to publish unless it comes with backlinks and if anything, they are supposed to be getting paid for what they publish, not the other way around.
