In Digg’s efforts to keep you swimming in their stream, they completely obscure the original URL you’re supposed to be looking at. And no, not just the URL you follow from a particular Digg on their site — all the URLs you visit (via clicks) until you kill the bar. Additionally, if you’re browsing around a site under the bar itself and you kill it, it transports you back to the original URL you landed on, thus completely breaking continuity and making it almost impossible to know where you’ve actually browsed to.
That’s the first sensible argument I’ve seen against the DiggBar — i.e., not from a whiny egotic blogger who doesn’t want his precious URL obscured, but from the standpoint of caring about the end user’s experience.
I used to have a <base target=”_top”> in my headers at some point; that’s a quite sufficient workaround. Not that I run any risk of ever being dugg.
