Do most people on Plurk refrain from using the prefixes when they speak and just use the freeform option? I just noticed I am one of the few who usually leaves it at the default (e.g. "Tesla Says").
It varies. Sometimes they happen as I use one that plurk picks up, sometimes I choose one. The one that is annoying is "is" - questions can start with it, but theplurk screws it up: Orvan [is] that a neutron?
