<i>Content shifting around is right up there with pop-up ads in terms of user frustration.</i><p>I disagree, especially with the almost complete absence of any progress bars or loading indicators that the UI designers seem to love so much and have forced newer browsers to have. &quot;Something happening&quot; on the page is nice way to know that it is still loading. A white screen is worse.<p>(Then again, I&#x27;m used to pre-Webkit Opera, which has a very prominent progress bar and applies CSS as it loads.)
