I think what Brian and the testers are missing is that 15k is neither big enough to be impressive nor small enough to be inviting.

How do I get email addresses for email marketing
Your blog provides a great way to build a personal relationship with customers and prospects — and to gather their email addresses.

Require blog visitors to provide an email list in order to leave comments, and set it up so that they have to actively opt out if they don’t want their email address included on your mailing list.
