Yeah, what you're seeing there is the delay while the app loads your user information
from the Flickr servers.
Technically, you're "logged in" from the instant you start the app, because it has in
memory the token that's used to access your Flickr account. But in order to display
information about you (like your buddy icon, the number of photos in your photostream,
etc.), it needs to get an update from the servers. And that takes a few seconds.
I'm working to see if there are things I can do to speed this up -- or at least make it
less inconvenient for the user.
