I've set up MailChimp campaigns several times - traditional sales lists, transactional stuff, software update notifications - and never thought of using it as a hosted/linkable newsletter. The "view this in your browser" link was always personalized for tracking, not semantic, IIRC. It did include the actual content of "Hello, {first name} {last name}!" tags, which obviously wouldn't work here for every unique reader. How long does this stick around? As long as you have a MailChimp account? I guess I assumed that the URL was unique per-user and would be deleted after 30 days, because the primary use case of Mailchimp seems to be not-quite-spam "We're having a sale!" bulk campaigns.
