If you have some knowledge to share, then why publish it in a peer reviewed journal rather than the quicker and easier route of just posting it to a blog? Dr. Annette N. Brown answered this in her excellent article, “Why should practitioners publish their research in journals?”
Brown’s article became a real life example of one advantage of journals. She published it as a blog post in 2017, and it is no longer available on the blog or anyplace else I can find on the internet. This is despite the fact that it is a valuable article and has even been cited in peer reviewed literature. By contrast, articles in journals are preserved permanently in the redundant collections of publishers, libraries and archives. As Brown wrote, “If the question is salient enough to do research, and the research findings are credible enough to disseminate publicly, then shouldn’t we make sure they enter the permanent, searchable, public record?” Since Brown’s article isn’t in that permanent public record, you can read my personal marked-up copy here: https://publishpeerreview.org/wp-content/uploads/2025/03/2017_why-should-practitioners-publish-their-research-in-journals.pdf
Brown pointed out two other advantages of publishing in peer reviewed journals. First, it increases the credibility of the research. As she wrote, “Submission to a peer-reviewed journal is an important signal, both that the researcher feels the work is of a standard to be published in a journal and that she is willing to undergo rigorous external peer review.”
Second, publishing in a peer reviewed journal increases the credibility of the practitioner. Brown cited her own experience, “Over my career I have recruited for hundreds of short-term and long-term positions for USAID and other funder proposals and projects, and while a record of journal publication is rarely a necessary credential, it is often a favored credential.”
