I find it somewhat ironic that both the Web Standards Project and advocate Lachlan Hunt updated their sites recently but failed to meet one of the goals of the web: that Cool URIs Don’t Change. Even if they did find that the URIs had to change, there are ways to prevent the existing ones from disappearing—but that’s exactly what happened to their feed links.
On a related topic, both sites also failed to preserve their unique item IDs in the new feeds.
Both are subtle points that affect what’s most probably a tiny minority of users… but is it setting a good example that they don’t/can’t/won’t take these implicit standards into account?
I don’t claim to be perfect in this respect—I have no idea if my feed item IDs changed when I last upgraded WordPress, for example, although I bet they did—but I’ve got a plethora of 301 Moved Permanently redirects on this site, my old one and others I manage to keep old content available. And both WaSP and Hunt kept the bulk of their URIs constant/redirected, so they’re still better than 99% of the other sites out there; the only reason I’m picking on them is that I just noticed that both feeds were dead.
