I'm a proponent of RDFa, but I actually see this particular behavior as a
bug, not a feature. Because the RDFa is hidden, you can easily copy text
from the Web and paste it somewhere where the hidden tags will make
incorrect assertions.

For instance, when I copy and paste a co-worker's name into a page on my Web
site, it would copy the foaf:name property. The foaf:name property worked
well on my coworkers Web site, where the foaf:name took the URI defined in
the parent element as it's subject. However, when I place it in an arbitrary
position on my page, it will then take another element for it's subject...
for instance, it might be pasted into a div about me, in which case it would
assert that my coworker's name is also my name.

I'd be interested to hear what other's think about this.
