I'm not sure how useful an email address is as a shared secret. If you
use a publicly-known one, anyone who knows it can spoof your signature;
if you use a unique address per service then you need multiple

Your long hash reminds me of the original Technorati claiming model,
which was a hash of the user ID and blog URL, which I deprecated as the
ID's were too long and cumbersome to send around easily - urls with
them in tended to get wrapped in email, so people ended up making their
blog invalid by adding a url with a newline in the middle, and my
parser had to cope with that.
Hence we went to a 10-character randomly-assigned ID model, as the ID
is not guessable.
As Chris said on his blog, the bidirectionally-verified rel="me" is a
sounder way to do this - see http://gmpg.org/xfn/and/

As your model is spoofable if I know your email, I'm not sure what this
gains for you over showing the ID or email directly in the moderated
