In some areas it’s usual to publish the preprints, for example in the arXiv: http://arxiv.org/ “Open access to 909,134 e-prints in Physics, Mathematics, Computer Science, Quantitative Biology, Quantitative Finance and Statistics”
In some other areas, the journals have more strictly policies, and don’t like preprints, reprints, free author pdf copies, ...
I’d really like to see a peer-review article, even if that means waiting to see the research data. There is a lot of bullshit inside per-review articles, but there is even more bullshit outside per-review articles. A per-review is not a guaranty that the article is correct, but at least it guaranty that some expert in that area had read the article and had no found any major fault.
In a fair amount of Biology and Medicine, it's not at all common practice to place a pre-print in arXiv. It doesn't surprise me even a little that the folks here haven't done so.
