I find that Associated Content is a great platform for earning if you know how they work. I'm averaging $100+ a day with them right now. Like previously stated, the fact that they pay through Paypal is a big plus too.
Like I talked about in another thread, they're also reviewing articles and making their payment offers much faster than they have in the past. I've been getting my reviewed by the editors and offers posted within a few days of submission. They used to take as long as 10-12 days at times. I think they finally decided to hire more staff editors.
