They may look cool on the surface, the URIs at Digg, but underneath the surface they are quite a lot more unfriendly. Not that this is really a surprise though, Digg doesn’t exactly shine when it comes to being web-friendly.
Earlier today, that new URI showed up in my aggregator. I opened the link in another tab of my browser, and was soon greeted by a rather disappointing message, including the word “Oops” and words to the effect of it being a symptom of a missing page.
Searching Digg for the story in general terms brought up the usual Digg dupes, but also what appeared to be the story I has been looking for, only with a different URI.
Compare this with exhibit A, and you’ll find that the post title hasn’t changed, but what has changed is apparently the categorization of the post — instead of being filed under “Tech News”, it’s now filed under “World News”. That little change makes a big difference. While the change of category assignment doesn’t itself offer problems, it evens seems reasonable, the change of URI certainly does. It is obviously the same resource, so to change its identifier is a no-go.
But wait. It gets worse.
You’d think they would at least then redirect from the “old” URI to the new, making this entire post moot, and offering a pleasant user experience, but no. Instead we were shown a generic error page, offering no assistance in finding what we were looking for. At the very least they could have included a link that would make it easier to find the story in question.
But wait. There’s more…
That’s the URI we end up with, showing the message in exhibit C, when following the link in exhibit A — a URI that may look cool, but really isn’t.
Usually, when you follow a link that is invalid for some reason, you get to keep the URI of what you were looking for in the address bar. As in this case, when you are presented with a less than helpful error message, you really could have used the URI for just a hint of what to do next.
But wait. It gets even worse.
I saw the original URI in my aggregator, because a lot of people had dugg the story. Some have likely submitted the URI to their blogs as well, making the URI quite widespread, not only directly via Digg’s RSS feed, as in my case. This means that robots will go look for the resource as well, and they will of course get presented with yet another view.

Not a 302 to the new URI, not a 404 indicating that it was missing for some reason, not a 410 telling it was gone, but a 200 OK — an error page…
It’s a good thing Digg doesn’t offer tagging, or their URIs would be changing by the minute, exploding the number of published URIs and disrupting the space-time continuum…
