How it works

The vast amounts of user-generated content on the Web often produce information overload as frequently as they provide enlightenment. Twitter Weather reduces large quantities of text into meaningful data - and visualizes the prevailing mood by rendering a weather-report-style display. Positive and negative feelings about a topic are mapped to a "temperature" from 0 to 100. '?' means that there is not enough data to analyze. Supporting Twitter Weather is a user-trained Web service that aggregates and ranks emotional content on a topic. Please rate a tweet or 10 to help us improve Twitter Weather.

Comment weather

Experimental comment weather bookmarklet for (currently) the Wall Street Journal and Engadget (and some other Weblogs, Inc. blogs). Drag that link to your toolbar, and when you're reading an article, click on it to get the emotional weather of the comments at a glance. Note that Internet comments tend to be negative, so think of it as the climate in London in March — 50 degrees is a great day.
