In reference to the comment about Blogger lasting 80 years, I am not assuming that nor will I ever think to even record everything publicly. For those who didn't notice, the posts are very old, even before my first post on blogger. They are "safe" and hopefully interesting excerpts from my numerous paper journals. And Blogger isn't a replacement, it's just a public bulletin board for me. I still continue to write in a paper journal. Perhaps I will switch to digital later, but there are many things that of course can not be written publicly.
