This is just one very cool site: LoveLines.
Through large scale blog analysis, Lovelines illuminates the topography of the emotional landscape between love and hate, as experienced by countless normal humans keeping personal online journals.
Using a data collection engine created by the artists for their recent collaboration, We Feel Fine ( www.wefeelfine.org ), Lovelines examines thousands of blogs every few minutes to find expressions of love and hate, posted by all manner of people. When it can, Lovelines identifies and saves the age, gender, and geographical location of the person who wrote the post, and then presents that information along with the post. The entries range from frivolous to profound, offering a glimpse into the hearts and minds of people blogging about their wants and needs.
It's just mesmerizing.
