I just wonder who nowadays still considers publication in peer-reviewed journals as a criterion for scientific relevance and quality? In my opinion only those who want to be patronized in making up their own judgement. If you want to make a qualified judgment you have to work through the article yourself and it doesn't matter then if it has been published in a peer reviewed journal or somewhere on the web.
Peer reviewed publication is not only very slow but also unjust as the number of papers accepted are dictated by the printing and publishing capabilities but not scientific quality (most journals have fixed percentages for the manuscripts that are being accepted for publication).
Besides, the scientific quality of papers has become rather secondary now. The standing of a scientist is very much determined by the sheer number of articles published (this is what determines monetary funding). Most papers published are thus scientifically worthless and redundant.
Even if non-mainstream theories are being published in peer reviewed journals, they may not be taken seriously or being ignored completely (like for instance my own paper regarding the
Scattering of Radio Waves by High Atomic Rydberg States which, although being quite revolutionary in its claims, received zero response as far as I am aware).
So I would say forget about peer reviewed publication. It is a thing of the past which was in place largely due to practical considerations associated with print publications, but looks quite out of date now. Online publications don't need to be refereed in any way as everybody sufficiently competent should be able to make up their own mind about it.
