If you're a dev and you self host your blog, I'd love to hear why. Why do you self host blogs? For most simple blogs in this day and age, migration to a static site like Jekyll or Octopress is pretty easy. I did this a while back. This can be followed up by asking Amazon S3 to host your website. You can even get cloudflare to front the SSL for free.
Why? S3 is free for the first year. Even post that period, my bills have been <$0.02/month which is a 99.951% reduction in cost.
