This is more a disagreement about the value of URLs than about whether Microsoft "cares" about their end users. With a keyword bookmark for Wikipedia, I'm about 50/50 for getting the content I want with simple URLs; I still wind up in the Wikipedia search bar all the time.
For me it's not about finding the information by typing in a URL. It's more about scanning and having a clue what I'm going to see by the url I'm clicking on. A giant random number really has no meaning or value in this context.
HN isn't a reference work like Wikipedia or the MSDN Knowledge Base, so it's less important here.
But the real reason that Microsoft's URLs suck is that the MSDN Knowledge Base is an older product than Google's, built back when the web was new and people didn't realize that their URLs sucked. And one thing that I respect Microsoft for is actually caring about reverse compatibility.
(Sidenote: This is why you should think about your URLs. They are how your website will be presented to the world.)
I didn't mean they don't care about their end users, I meant they don't care about their URLs.
I think the links earlier in this thread are a perfect example of why this is useful. You can tell what you'll get when you click on the Yahoo! and Google ones, but the Microsoft one is totally opaque.
Nobody has a foolproof scheme.
