answer:I have done some writing, but never as a free-lancer, so I may not be of much help. But it seems wrong to me to shop the same general subject to multiple places at once. My thinking is that if the first place catches on with you, they may want additional stuff on the same subject, and you will have foreclosed that possibility by offering to/selling to the others. But in the best case, let’s say you sell to all three. The problem there is that you have boxed yourself in on subject matter. You’re now the expert on “XYZ” to the point that you have three articles to your credit. You may have narrowed your future sellability by having so narrowly defined your area of expertise. So for those two reasons, I would submit on different subject areas to the other two.
