Incorrect, Facebook or the company that kills Facebook will figure out how to convey multiple identities from a single account.

Facebook will soon enable us to better manage multiple identities in the same way that Outlook's delay send feature helps us with working all hours of the night.

Eventually photos from your xmas party will only be viewable by your coworkers and photos from burning man will only be viewable by burners.

There have been ways to manipulate facebook to do this for at least 3 years, but maybe longer.

It used to be that only "Really good friends" could see nearly anything on my profile, but I ended up relaxing things and creating a list of "Sensitive People" who are blocked from almost everything on my profile.

Facebook already allows you to group friends together and assign permissions based on those groups. I can post a status update right now that everyone except my family can see or a status update only my high school friends can see.

Yep, it is a bit of a PITA to setup but once done is well worth it in avoiding social faux pas.
