> Nobody should be self-hosting unless they know exactly what they're committing to.

it is just a FUD. Self-hosting can be done in a range of options - starting with your personal webserver on your own home or collocated computer (geek) to the pages personalized with your domain name on some common hosted and managed _open_ platform like wordpress, etc... (regular, non-geek person)

The issue isn't about technicalities of hosting or data portability. It is about content ownership. What FB does is "all you base are belong to us".
