There's considerable consternation in the SF blogosphere and among members of a newsgroup I subscribe to about the demise of Sci Fiction. The aspect that fascinates me is what happens to defunct websites. Ellen's earlier sites Event Horizon and Omni Online eventually vanished; what will happen to her section of SciFi.com? Presumably the corporate entity that runs the cable TV channel will be around a while, so at least the domain will be around a while, but still.
Some have pointed out the existence of internet archival sites, e.g. the Wayback Machine
. I've found old content of Locus Online there occasionally, but some people report that the coverage is spotty and the site difficult to use.
I can't help but think of the consequences of various apocalyptic scenarios, the plague, the war, the collapse of the biosphere, leaving us all huddled in pre-industrial hovels. In such cases moldering paper magazines and books might still be found. But the electronic infrastructure will have vanished into the aether. I suppose in such cases, that will be the least of our worries.
