Facebook has gradually added different tags to its "Status" updates.Currently, most users have the ability to tag: who, when and where.Those options could soon include: what. (Roll out is limited at the moment.)And not just what you are doing — but what you're feeling.As long as everybody you're friends with gets the joke……you should be safe.But let's say your boss mistakes "a pan galactic gargle blaster" for a real drink and reprimands you for drinking alcohol on the job.That could leave you feeling quite annoyed.How do I share my feelings or what I'm doing in a status update?Carefully.
