I've just delved into the stackauth methods for the first time today, and I can't help but notice that there's no real URL friendly key exposed.
For example, I want a unique URL for each API endpoint in my app, so that it can be bookmarked. E.g. http://www.column80.com/?site=stackoverflow
But none of the keys provided are any good. name has spaces (who wants a %20 in their URL?). site_url is even worse for including in a URL (it contains http:// etc), and you haven't specified that the index is reliable (and even if it were, http://www.column80.com/?site=1 doesn't mean anything to anyone, especially not if you want to do SEO in the future - and it means doing a for x=... loop instead of a for each loop).
So my only option at the moment is to roll my own, which is
- Annoying
- Unreliable
- Slow(er than it has to be)
A unique key would fix that, because keys can be descriptive, and generally don't contain spaces, and even a 3-letter (mso etc) key is more descriptive than 1
