Well don't use me as the voice of reason, but I have one with blogspot.com. I think most people use it as it is fairly simple (once you play around a bit) and I think it is set as private only, then add/invite friends to view.
Ours is still for us until we get to NZ as it is parts of our story so far, we will add better moments when we arrive and let our family see it then. - don't want them worrying over our problems until all is resolved.
