This blog, like a lot of other blogs (I was going to say of note, but that's a little presumptuous) is hosted for free.
Free hosting of course means there is no obligation on the provider to keep hosting as in the case of yahoo and geocities.
Well I used to have a blog on journalspace. I don't any more - it's gone, and JournalSpace looks now to be a wordpress based hosting site using wordpress-mu just as we do.
Whether it's gone bust, been taken over in GFC I don't know.
Anyway it's gone, along with two years or so of my posts and notes. (Which to be fair I referred to rarely, which is why I didn't notice its demise).
Fortunately I do have backups of most of the content so I'm not stuffed. But is does beg the question with so much discourse, scholarly or not, making use of hosted services, what happens when a service dies?
