Years ago the site was uncluttered and was able to present large amounts of scientific data in a single screenful effectively and without being overwhelming. You could quickly access, find and visually scan data. Now it is a mess of jumbo display elements that require lots of scrolling. A single metric such as pollen index now requires about half a megapixel of display space on my monitor. The site has become sluggish and there are so many functional defects. Even simple things such as differentiating the units of temperature seem to be beyond the capability of the site's developers now. If they rolled back to about 2005 a huge proportion of their user base would be extremely grateful.
