Here's a URL that is unique to me:

Those URLs are not OpenIDs, but are usable as UIDs. It's not really difficult to find such URLs; almost every site you use with an account creates a URL that identifies you and only you.

Hello Scott.. OK that's community blogs and wiki's dealt with.......

I can use that same URL as my UID on any site, not just blogs and wikis. Whenever I find myself stating something that seems obvious like that, I start to suspect there's some larger misunderstanding underlying the discussion, but I have no idea what that might be. Real world examples are a good way to reveal hidden assumptions...

many people share urls with other people

Sure, and such URLs should not be used as UIDs. The use of URLs as UIDs does not suggest that *every* URL makes a good UID, just that there are enough to be usable.

Agreed, some people still may not have any choice.

Maybe; maybe not. Let's not solve hypothetical problems. If you've actually seen this problem in practice, please point to it so we can all talk about the same thing.

Peace,
Scott
