There is loads they need to address, and they do themselves no favours. A little bit of slowness in the main site is OK if hardly shining, but the discos etc are detrimental as well as all on them when it's so wide.
For the sake of 30 seconds switching to a different browser to solve a little meter stutter ( as especially potentially likely after an update being flash or WGT), and solving that one for 3 months..............That has simply just worked for loads so well worth trying for that one issue at least.
