On Being More Aware of Defects

When I used Yahoo! Mail through the Web, I was not always aware of when it was "suffering," whether going through a minor hiccup or just plain crashing. The only thing I came to realize was that, when it got into such a state, it could bring down Safari because its page needed to be reloaded, the only way of letting me know that it needed my login information again. Now OS X Mail tells me whenever Yahoo! is not communicating! Most of these are, indeed, short-lived hiccups; but it means that Yahoo! now does less damage to Safari!
