The good ol' Subdomain-versus-Subfolder debate just gets a bit more expensive on the left side, that's all. Services that really need an unlimited number of subdomains are a tiny minority, and market prices reflect this. For the time being, someone like WordPress.com can probably afford $60-$100/year for a wildcard certificate. Everyone else just sticks to subfolders like Twitter does. After all, nobody will be preventing you from running a website. Your priorities and economic circumstances might prevent you from using pretty subdomains, but that's no different from the current reality where short and memorable dot-com domains cost thousands of dollars.
