While open access journals do encourage the dissemination of ideas, they are by no means without a cost to the researcher who produces the work. While open-access journals may be free to read, they are not free to publish in. On average, open access journals cost around $1500 per article. That's $1500 the researcher has to pay out of their grant and the taxpayer is paying for out of their pocket. While I'm all for open access journals, as a researcher myself, I know how difficult it can be to pay these exorbitant fees from the grant money I was awarded to do research. It comes down to whether or not I want to do an experiment or publish a paper, and I shouldn't have to make that choice. Having the option to publish in a traditional journal frees up much of my research funds for doing what it was intended for: research. These journals have good intentions, but the tax payer is paying for them in the end. Personally, I have very mixed feeling when it comes to open access journals. I publish in them when I can, but if it means sacrificing an experiment, you can bet I'll pay. Until the publication fees drop, I don't see widespread adoption.
