What would be nice is if companies that run hosted blogging platforms would allow someone you designate to inherit
your blog, with the ability to continue publishing it, rather than them just getting a copy of the data with the blog ultimately deleted.
I have one blog up, primarily with the intention of it serving a reference for my daughter, beginning after she has moved out, gotten married, and started a family of her own, but also as a "safer" than dead tree archive of a specific type of information that tends to get lost when someone dies (recipes). We are deciding together what gets put on there. I placed it on what I believed to be a stable free blogging service, to avoid the possibility that it would be deleted for nonpayment, in the event of my death. I have even recommended
that others do the same.
Being able to inherit that blog and add to it would mean that she could continue it with her own recipes. I think what I will probably end up doing is adding her as an administrator, giving her the ability to add her own recipes to the collection, now, so that way she would still have control over it later on. I think that's about the only way one currently can "inherit" a blog hosted by Google.
