Seems London Fire Brigade is considering twitter to report fires...

Is that any more reliable than SMS?

You can see if a tweet has been posted, and unless there's a system-wide
outage (which does happen very occasionally) it's reliably almost
instantaneous.

I can tell this because I have three Twitter accounts linked to my
Tweetdeck and one follows the other two, so I can see the messages
coming straight back.
