Medium

Medium is a publishing platform rather than a directory: products get discovered through the story around them — a launch narrative, a technical walkthrough, a lessons-learned post.

Publishing is free and immediate with an account, with no editorial gate and optional scheduling. Links are platform-controlled and nofollow.

DR 94 with an estimated 31M monthly organic visits makes it the largest surface in this set by a wide margin, but reach depends almost entirely on which publication picks the piece up. The bare link is worth little; the distribution is worth a lot.
