Techurls.com – Read tech news from the most popular tech websites in one place

I'm not sure how the popular websites were selected.
Perhaps the author of the site can answer your question in the comments of the corresponding blog post. http://www.catonmat.net/blog/announcing-techurls/
Three factors I view as appealing, versus navigating to each site separately, include 1) the aggregation itself has value (e.g., to save time), 2) the primarily textual interface and 3) the search functionality.
