So how are the articles ordered? Does this order change over the course of the day? Sure it's a great way to expose me to tons of info with very easy eye movement, but it's also tons of real estate. How do I re-find an article or is that not really a problem? If they're not going to foster user added content, then no; if they are, then it's a big problem. I sure hope they also have a sortable list view (by post, by title, by author, by location, by popularity over a time period). They have a big challenge and I agree than the present form could be improved, I'm just not sure this is the only best way to go. Nice to see them pushing the envelope a bit though as it shows the get it and want to improve- two plusses in my book.
