I finally got Next 13 to work on Vercel

!!! Don't use the SRC folder otherwise the absolute import of components will work like hell (whereas everything works fine on the local computer). Too bad the Metadata function doesn't work in 'use client' pages so you have to create a local layout.jsx to get around this. If you use the useEffect hook to get data, then you can't use Metadata to create meta tags dynamically (for example, from post titles and descriptions). But Next 13 has a great future if they get it right.
