This is an old article from last year, but I see the feature has been added back in Twatter. Their excuse is this is a tool to help when switching between personal, and branded accounts. Now how many folks in the general populace also have a brand to manage?

It seems to me a tool most advantageous to bot-farm managers, and people with sock-puppets they use to bolster their arguments / self-image online. Somebody should call Twatter out on this – clearly to help 'bots…any opinions on this?
