On your own network profile, there's a tab to access your combined flair:
I was curious how another user's flair would look like. Some include it in their profile, but if they don't, I can't find a link to it. Is this on purpose?
Note that it's possible (also mentioned here) to change the URL to go to the 'flair' tab: https://stackexchange.com/users/620/shog9?tab=flair
but the text is rather odd if it's not your own profile you're looking at (which makes sense, for a non-publicly-linked page).
