I agree, particularly in the email case.  It's important that semwebby
people don't "look down" on these string-based forms of information.
The hunger for URIs and links and network effects etc can sometimes
lead us to forget that these other idioms are also valuable in their
own way... and that sometimes (eg.) it's more expressive to give users
a plain text "favourite movie info" field where they write a few
words, than to force them to give an ordered ranking of precisely
identified movies.

cheers,

Dan
