Recommend me a blogging site

Sorry if this should go in IMHO… I thought GQ would be a better fit.

I’m looking for a blogging website that will allow visitors to read my posts and leave messages without being members of the site themselves. I don’t want to burden any of my friends with registration just for li’l old me. Here’s the problem though… I don’t want it open to the whole internet. What I’d like is some sort of simple code or password to give to my friends in real life so they can have access to it on the fly, for instance a single password field next to a comment box and a place to type a name. That would provide a little privacy for me without making each of them register on this site and maintain yet another login and password.

Does any such site exist?

Thanks!
