So what happens later
Wow, that title scared me! And then I thought, I wonder if something happened to Sheldon? His website has just been so useful and his writing style so friendly that I feel like he is a friend even though I have never met him!
Are there provisions for the site in case there is a problem? Are there backups? Has anyone ever asked him about porting the stuff over to Wikipedia or somewhere else eventually? I have seen so many useful websites just vanish because of various circumstances (hell, I used to maintain one for kendo that I lost because of database woes).
