Should I email my posts, too?

I’ve been off Twitter for about four months now (!), I don’t track analytics for the site, and I don’t have comments, so I’m completely blind to how many folks actually follow along with the blog. Occasionally, I wonder, but the writing is honestly more for me than anyone else, so it really doesn’t matter at the end of the day. At the same time, I wonder if it’d be more convenient to receive as an email. Would you “subscribe” to receive the posts in your inbox, or is RSS enough? Let me know.
