great question! Sounds like i should turn it into a post.

A loyal reader is more valuable than a 'part-time' or first time reader. They could click off your blog without earning you any money and never come back. Or click adsense and be gone forever.

By getting a subscriber they continue to read your articles and get involved in your website. Not only that but say you plug an affiliate etc, they would be likely to join. Things like that.
