I kept getting the same results each time I hit "more." I got excited when I read the title. I thought it might actually be obtaining data from those sources in real-time. A quick glance at the status bar showed otherwise.
the 'see more' link on search results with a single response repeats the result. So if i search X and Y comes up when I click 'see more' it shows a list of Y, Y. I assume this is just a small bug.
