I shall allow my users to have multiple profiles in my website, to allow them to impersonate identities they create to post. But I have doubts about the best way to accomplish this.
Assume that I want to make it easy for my users to quickly switch their profiles during their session, they will probably switch multiple times during a single section.
In the wild, Gmail let me switch between accounts by opening a new window, but Facebook allow switching your "persona" (you or a page) displaying a hint and changing your avatar but keeping you in the same window.
Which way does users fell more confortable? If none, how this feature should be designed for a best experience?
