Sure. People post them all the time. Most are HN clones. All of them die with a whimper after the initial HN juice is gone.

The problem isn't technical, the problem is that social media and Reddit already do what people wanted forums to do, and did it better in many ways (albeit at the cost of centralization and homogeneity.) There is just no niche in the web ecosystem for old-school forums anymore, other than appeal to nostalgia.
