Why I’m on Substack

By Billy Cooper

I’m on Substack because attention has shifted, and when attention shifts, thoughtful lawyers need to decide whether they are going to follow the crowd late or move early with intention.

Substack has quietly become one of the most important publishing platforms on the internet. It is not built on noise. It is not built on chasing trends. It is built on writing, ideas, and direct connection between a person with something to say and people who genuinely want to read it. That distinction matters more than ever.

For years, law firm marketing revolved around websites, search rankings, and social media feeds that none of us truly control. Then came newsletters that felt obligatory, podcasts that required production teams, and short-form video that often prioritized performance over substance. At the same time, AI systems began summarizing articles and answering questions without sending readers to the original source. The digital landscape fractured, and with that fragmentation came opportunity.

Substack sits at the intersection of publishing, email distribution, and discoverability. When I write there, my work goes directly to readers who have chosen to receive it. There is no algorithm quietly deciding whether my thoughts deserve to be seen. There is no dependency on a third-party platform that can change the rules overnight. It is a direct line to an audience that values depth over distraction.

What surprises me is how underestimated this space remains in the legal world. Many firms still treat content as a checkbox. A blog post written primarily for search engines. A LinkedIn update because someone said we should be active. A quarterly newsletter that reads like a press release. Substack rewards something different. It rewards perspective, clarity, and consistency. It rewards lawyers who are willing to explain how they think, not just what they have won.

And right now, relatively few lawyers are doing it well.

That window will not remain open forever. We are still early enough that a lawyer with a focused voice can stand out quickly. Journalists can find you. Other lawyers can understand what you care about. Referral sources can see how you analyze problems. Over time, a Substack becomes a living archive of your thinking. It shows not just your résumé, but your reasoning.

I am not on Substack to go viral. I am there to build a body of work. When someone wants to know how I approach pedestrian injury cases, or how I think about insurance defense tactics, or why certain cases matter beyond a settlement check, they should be able to see that thinking in long form. A website bio tells people what you have done. A consistent publication shows them how you think.

In the age of AI, this becomes even more important. Search engines and large language models increasingly surface authority based on depth, structure, and repetition of ideas across time. Long-form, thoughtful writing is not just read by people; it is indexed, analyzed, and referenced by machines. If your firm has no meaningful publishing footprint beyond a static website, you risk being invisible in a world where digital authority influences who gets surfaced, cited, and recommended.

Clients, meanwhile, are not hiring résumés alone. They are hiring judgment. They are hiring conviction. When someone is injured and trying to decide who to trust, they are looking for signs of clarity and confidence. They want to know whether the lawyer they are considering actually understands what they are going through. Substack allows that voice to come through in a way that traditional marketing rarely does. It creates room to educate without selling and to explain without oversimplifying.

There is also something refreshing about returning to writing itself. No shrinking arguments to fit a character limit. No chasing trending audio clips. No compressing complex legal issues into slogans. Lawyers are trained to analyze, to argue, and to persuade. Substack gives those skills a modern, durable platform.

The legal industry will eventually catch up. More firms will realize that building an owned audience is not optional. More marketing teams will recognize that long-form authority compounds over time. When that happens, the space will become crowded, as every valuable platform eventually does. The firms that started early will have years of searchable, citable, structured thinking behind them. The firms that waited will be playing catch-up.

I am on Substack because I believe in the long game. Because I want to speak directly to readers without filters. Because I believe legal education should be accessible and honest. And because building authority in public, one thoughtful piece at a time, is far more powerful than declaring it in a tagline.

In a world where trust is built digitally before the first phone call, the question is not whether a lawyer should be publishing in a serious way. The question is whether they can afford not to.
