I am self-hosting this Ghost instance.

If you subscribe to receive emails, your email will be saved on the Ghost instance, and I will use it to send you emails. Shocker. I'll back up my data - including your email - so that I can recover from failures.

If you'd rather me not have your email address, you can subscribe with rss.
