I noticed that the profile page is only viewable when a blog is specified with it. Is this a "feature" or a bug? Since profiles are independant of blogs it seems like one shouldn't rely on the other. Is it possible to show the profile page without a blog being specified?

My main reason for asking is that I want to send users to the profile page after they login for the first time. I have to specify a blog ID in the redirection URL, but how can I be sure that blog exists? It's nearly safe to assume that blog #1 will be set, but there's no absolutes with database autonumber IDs... It would be more future-proof if I didn't need to declare a blog ID at all.
