A few comments:
1 - He has published it, on the web, otherwise you would not be able to read it.
2 - Publishing something in a peer reviewed journal does not make something inherently better, or worse.
Peer review is not some kind of mystical spell that you cast on results to make them "scientific". Peer review simply means that peers, people working in the same fields as you, have gone over the results and agreed with them. Typically, two, to the author anonymous reviewers, go over the paper, after an editor has had a look to see that it is fit for the journal. You might be interested to know that neither Nature, nor Science practices such peer reviews. The editors of those journals accept or reject the papers themselves.
However, in any scientific field, there are only around 150 peers, Dunbar's number. When a field gets larger, it splits into several sub-disciplins. The big problem with the peer review system, both for results, and, very importantly for grant applications, is that all peers are in the same boat. So only results that generally agree with the field will be accepted. If a young brilliant scientist wants to publish results that show that the whole field is a dead loss, that there is no chance it will cure cancer and the like, he is unlikely to be published. He will not receive any grants for a proposal that sets out to prove that all of his peers should change profession, because the field is a dead end.
To fix the problems with peer review, we need competition. Independent funding from many different sources, and preferably none at all from governments. Terence Kealey discusses in a couple of books the empirical fact that for civilian research, for every dollar that the government provides, 1.25 dollars of private money disappears.
