I know bashing PayPal is cliché by now, but its UI is seriously one of the worst I've seen for an internet service. Everything loads extremely slowly, and every action is buried inside multiple layers of navigation, which only compounds the problem.<p>What's more, you often cannot choose how many items to display per page or even search by keyword. This ensures that you have to click through page by page, enduring the slowness each time.<p>They're obviously aware of these problems, but the fact that they haven't fixed them in years would indicate that either their codebase or their organization (or both) is very inflexible.<p>Forget about destroying violins, for me this inability to adapt and improve their product is PayPal's main problem.
