Five reasons blog posts are of higher scientific quality than journal articles, by Daniel Lakens.

It is my opinion that blogs, on average, score better on some core scientific values, such as open data and code, transparency of the peer review process, egalitarianism, error correction, and open access. It is clear blogs impact the way we think and how science works. …

This shows blogs can be an important source of scientific communication. If the field agrees with me, we might want to more seriously consider the curation of blogs, to make sure they won’t disappear in the future, and maybe even facilitate assigning DOI’s to blogs, and the citation of blog posts. …

There is no intrinsic reason why blogs should have higher scientific quality than journal articles. It’s just that the authors of most blogs I read put some core scientific values into practice to a greater extent than editorial boards at journals. I am not recommending we stop publishing in journals, but I want to challenge the idea that journal publications are the gold standard of scientific output. They fall short on some important dimensions of scientific quality, where they are outperformed by blog posts.
