If you're wishing your writings to be read by your children, why not print them on paper — and so in duplicate amounts kept in different places — that they will eventually find?

I think, in your case, it would be easier to keep physical copies of those texts than try to keep a digital version of them up for a hundred years. And far less expensive.

Also, you'd be leaving them a more precious thing. I'd be far more excited discovering papers that my father/mother wrote and left for me than, say, seeing them on the internet.
