My pet peeve is that /foo/primary_key makes computers happy... but not
people.

/products/23
/products/ABC-1234

The first is the PK for a product record..
The second is the actual sku for a product... just a unique as the
pk...but not the PK itself...

Now what does "id" mean in this case?
What id your SKU is a numeric just like your PK?

Two different and equally useful ways to get at the same resource.

If you're talking about an interface where humans know the skus, and
computers know the id (restfully and/or remotely).. you need a sane uri:

/products/id/<id>
/products/sku/<sku>

In the end, I always run into a situation where humans (think marketing
SEO pushers who know not of REST) want something other than a true
restful uri.
