How rivals are picked

Every square's description is compared with every other square's, and the closest thirty are read by an AI that keeps only real alternatives: products a customer would weigh against stemjson.com. Add-ons, companion apps and neighbouring niches are left out. It reads what each site says about itself, so it can be wrong; tell us when it is.

Bulldozing costs what evicting costs: double what the owner paid, $1 minimum. It's anonymous, nobody moves in, and the lot reopens at $1, so they can come back. The longer version is evict your competitor.
