re: London Firefighters Pursue Twitter Monitoring
I'm a little skeptical of the use of Twitter or 3rd party services to do something so important as report fires, ask for help, etc. The article states it's not meant to replace dialing the emergency number (999 in this case), but as a supplement. I feel this may pick up as a way to report non-emergency things such as minor accidents, but won't be very effective in emergency situations. If you need immediate help, using voice will always be a better option. If you have data signal on your phone, you should have voice capabilities.
