Yeah, when reading this, between the fact that I love emacs and the fact that I'm not too comfortable giving Ohlife (and Google, since I use Gmail) my journal, my immediate thought was text/markdown files backed up to a private Github repo.

But the email would remind me to do it every day, and it'll be easier to look through old entries on Oh Life since it shows all entires on one page (though I guess there's nothing stopping me from just having one super-long text file, if that's what I want).

At least they have an export that looks solid.
