Hello. I finally did it and signed up with Fortitude. So far, it's the writing site that makes the most sense to me. You have to pay less than $25 for annual membership, but that amounts to just a little over a dollar a month. It's an online magazine that publishes new issues daily. When you get published on the front page (determined by the number of good reviews your piece gets), they pay you anything between $10 to $100. If your piece doesn't make it to the front page, you still get a dollar for it. If you get to publish something everyday for a month, you've pretty much gotten your year's membership fee back. The fee is a means to stop people from gaming the system (making multiple accounts to give good reviews for their own articles, etc. I really wouldn't know.). Also, you are not allowed to give reviews if you have a piece up for review. This way, you cannot influence the outcome of the next issue's list of articles. It sounds pretty fair to me and the articles I've read are well-written. If you're particular about where your articles are published, it's safe to say that in Fortitude, they will be in great company. You also get paid $.02 for every review you give.
I do think Fortitude is the site that "behaves" the most like a regular magazine. I wish I had submitted my 3 Bukisa articles and 1 Triond article there, which in the past several months have earned exactly $.10 altogether. I'm pretty naive about gaming those systems and have no intention of learning, so I suppose Fortitude is the better fit for me. If you do want to take pity on me and view those articles though, the links are on my sidebar, thanks. They obviously also pay for referrals and I'd appreciate it if you sign up under mine: Get Paid to Write for Fortitude.
