It's on a public IP, but isn't open to public users. I don't personally think 'the place I scribble stuff I want to remember down the road' is a blog, but I'm equally uninterested in arguing a distinction I don't think much matters. I don't know what you mean by 'extra step' unless you mean 'loging in', which is a hurdle I assume I'd have to jump over if I was posting a blog entry.

Edit: hit post too soon...
