I used to love this game. Wonder why they keep these sites up? I mean looking at the domain it's hardly buried deep within the MS site...
In the corporate world, you just don't touch stuff if you don't need to. There's no time to go and find web pages that haven't changed in 10 years and figure out what to do about them.
Now I come to think of it I guess there may also be a need to keep it in place due to links from other parts of the site.
I'm going to go ahead and guess search-and-replace is their version of templating?
It's easy to manage a large site that only makes a few changes per week.
It's probably way less effort to just leave it here. It's not like it's using a lot of space, or requires some beefy performance anyway.
