There was a time when investors were shying away from niche publishing because “journalism” was “expensive” and user-generated content was “cheap.”

But as the world changes tides and begins to preach the quality over quantity sermon, investors have begun to appreciate journalism again. The “fake news” saga has only helped legitimate news publishers, because consumers have become more discriminatory about where they get their information.

The same logic applies to specialized information, and we believe in the quality of content created by niche publishers. But we’ve also noted before that by reaching that “very specific audience … in a deeply authentic way,” niche publishers are also able to deliver more and better leads to their advertisers. After all, if you make martial arts floor mats, where will your advertising dollars be better spent – at ESPN.com or BlackBelt.com?

And to go along with niche content, we’ve always admired a certain circle of industry leaders who pack a punch when it comes to singing the praises and sorrows of niche publishing and specialized information publishing.

Once you follow us on Twitter, you should probably read their work and follow them, too.

10 Niche Publishing Thought Leaders

1. Bo Sacks, Precision Media Group – @bosacks

For the past 25 years, Bo Sacks has been at the top of our list. He’s the President/Publisher of Precision Media Group and has been covering niche media almost as long as it’s been called niche media. Bo Sacks has held every prestigious title there is in the periodical publishing industry, and runs what he says is the longest running e-newsletter in the world, with 16,750 subscribers, called “Heard on the Web: Media Intelligence.” Bo’s focus is directly on the media, marketing, and publishing industries and speaks about “El-CID” or Electronically Coordinated Information Distribution. As part of his blog, he also gives credit to his readers, where he’ll frequently post his responses to what he writes.

2. Linda Ruth, PSCS Consulting – @Linda_Ruth

3. Samir Husni (Mr. Magazine) – @mrmagazine

With a nickname (and website) like “Mr. Magazine,” you might imagine what Samir is into. In addition to being a consultant, professor, and Ph.D., he’s the founder and director of the Magazine Innovation Center at the University of Mississippi’s Meek School of Journalism and New Media. His blog is filled with ripe information on the magazine industry and trends, but more specifically he does a lot of interviews with other industry leaders. He has published comprehensive interviews and has a knack for publishing wordy interviews and articles, and extracting their most meaningful or digestible quotes that make you think more deeply about every angle.
