Twitter is a bit strange service. At the first view it’s not useful at all and absolutely chaotic. But it offers amazing functionality for extending and delivering different type of messages. SimpleHelp posted 12 web applications based on twitter which can make your life easier. What you can do with those applications? Get information about some places from MultiMap or about current weather, know how much fuel do you use, send some message to the group of people, setup alarm, track your FedEx, UPS, USPS or DHL package, search for books, DVDs and music on Amazon.com, connect to your Google Calendar, Remember The Milk or eBay account. Really amazing, isn’t it?
BTW, I registered on the Remember The Milk and created a few tasks. Will see if it’s more suitable for me then Toodledo.
