The people writing about a problem are either buyers living it or competitors selling to it. Both are worth knowing about, and the difference is obvious once you read the posts.
The first is lead discovery: the authors themselves. Someone writing in detail about a problem is usually living it, and their post is the most specific brief on their pain you could ask for.
The second is pool discovery: finding the posts worth harvesting engagers from. Most of the volume in an engager play comes from other people's posts, and this is how you find which ones.
A topic search returns a mix of practitioners describing a problem and vendors marketing at it. The distinction matters and is usually obvious from the post itself, so the output keeps the full text rather than a summary that would flatten the two together.
Run once it is research. Run weekly on the same topics it becomes a monitor: which arguments are heating up, which vendors have started pushing a new angle, and which practitioners keep resurfacing. That pattern is more useful than any single run.
Skills compound. These are the ones we usually install alongside it.
