In a moment of boredom I decided to try loading the new site on my blackberry (Curve 8520). Giving it four times as long as it takes to load a British newspaper page, my browser showed 0k (yes, zero) of 3k loaded. Eventually, I ended up with a blank page with only a title of slashdot.
Granted, the main page used to crash my phone completely. I guess this is an improvement in that aspect but not in any way better at actually showing information.
And yes, I know my phone is old, but there are plenty of relevant sites that it works just fine with.
