Twitter

Imagine a Blog on which people are constantly updating their current activities. Twitter is a small application that allows a person to post what he/she is doing or thinking right now. It is a strange hybrid between Blog and Instant Message. It has become most popular as a widget that people add to their Facebook or MySpace web pages. Since many people uses these pages as their web home page and the basis for communications with friends or associates, they find tools like this useful for sharing real-time information. This is an application that does not really make sense to a traditional worker who does not use Facebook or have time to be constantly updating their personal status. But one interesting application might be to create remote sensors that are constantly posting their data through Twitter. Anyone interested in the information from that sensor would subscribe to its “twit” and be able to see what is happening. A user would probably subscribe to multiple “twits” and look for an aggregating tool that can pull all of these into a unified picture. In this case the interesting part of Twitter is the publish/subscribe feature over the internet.
