Hack-Resistant Blog

Not that this is a problem for anyone, but after reading a bit on web security, I thought about the potential that someone could hack into a high-profile blog and post false entries and/or mess with existing entries. It occurred to me that, if I started building an audience, I'd be quite buffered against this possibility since my entries are handwritten and generated & stored locally. I doubt a hacker would bother trying to mimic my handwriting, and I could restore it all from my local copies.
