I have not done any work or research in this area but based on
personal experience, I agree with Yohan for precisely the same three
reasons.
I'll also add the following for your consideration:
Despite being someone who has multiple email addresses, I would still
have an easier time figuring out which one of them to use versus
trying to remember which user ID to use (from the multitude of
variations that I have had to craft over the years based on the
different requirements each website has imposed).
As for email addresses changing...yep it's a drawback Am currently
noodling ideas for the best way to manage this on my end. Didn't think
about what sites could do to help.
First thing that comes to mind is something I've seen a few
times...providing for an alternate email address as backup. Still has
similar issues but it's a start.

The email address as user id is becoming the preferred way in my
opinion.
Pros:
an email address is unique;
an email address is easy to remember;
in many cases the system requires the email address also for sending
messages.
Cons:
still not everyone has an email address;
an email address may change over time.
Did you consider OpenID?
