When I went to the example links given at the end of the post with my phone, I jut got a "spinner" for several minutes before I gave up waiting...
On https://flipboard.com/explore I get some exciting but very distracting rendering artefacts (blocks on the images changing intensity at a high speed until I start scrolling fast - if I scroll through slowly, the flickering continues)..
If I click through on one of the example pages, scrolling seemingly randomly stops working smetimes (after a few tries, it started snapping back to where it was, even when there clearly is more content below).
This is with the Android browser on 4.2.2, admittedly on a rather obscure phone (a Kingzone K1 Turbo) .
