Hi Sean,
As the link there includes the elq, you would be potentially sharing the personalised version of an email socially, so I would be tempted to create a landing page version of the email and share that socially as you suggest at the end of your post.
An alternative could be 'forward to a friend' functionality, where the link would take the user to a form where they can fill in their friend's email address and the new friend is then dropped into a campaign to send out the email
Hope that helps,
Phil
