There are websites all over that have failed this morning. The error messages are many and varied. That's usually a sign that some huge relay has failed and that a computer in one part of the world can no longer talk to other computers and put together a web page.
However, I broke down and set up a Twitter account. I haven't had it for two days and already a person I can't remember where I met has started following me. Then again, she has a big list of followers. It might be that she just picked me at random. I dunno.
I set it up so I could stay in touch with family, not strangers and casual friends. I'll see what happens.
