Twitter Data Portraits

Lexigraphs I is the first visualization from the Data Portraits series. Micro-blog authors use mobile text messaging or web interfaces to post short answers to the question What are you doing?, creating a stream-of-consciousness account of their daily encounters, musings, plans and actions. Using salient words from an individual’s postings, we visualize the topical and temporal patterns to create a portrait of the author.

Gary Kovacs: Tracking our online trackers

As you surf the Web, information is being collected about you. Web tracking is not 100% evil — personal data can make your browsing more efficient; cookies can help your favorite websites stay in business. But, says Gary Kovacs, it’s your right to know what data is being collected about you. He unveils a Firefox add-on, Collusion, to do just that. (Update: Collusion is now called Lightbeam.)
