Simply put, Tweet Sentiments measures the happiness of people based on what they are posting to Twitter. If you give this new service a try, you will be able to see not only how any specific user has been feeling over time – you will actually be capable of gauging the happiness of whole countries.
And the site goes even further, as a chart will let you see how happy the entire world has been feeling as of late. This chart can be accessed on the homepage, and if you want to know even more then you can check both the ?Top 1000? and the ?Recent? tabs. These are found on the main navigation menu.
Besides, full integration with Google Maps is already provided. This means that you will be able to visualize everything in an even more contextualized way, not to mention that seeing everything in such a setting is far more enjoyable and easier on the eye.
Obviously, an application of this nature is not something that you could go blindly by. It is more like a reference tool that you have to take with a pinch of salt. As long as you keep that in mind, you will enjoy the site as it should be enjoyed.
