I don't know why people are so surprised about people comparing Porter to Stout. In Ireland Guiness is still often referred to as "Porter". Actually, Porter is sweeter than Stout but are close relations.
The name Porter allegedly comes from the black beer drunk by the porters of Covent garden Market in London. During the 18/19th Century there was a fair amount of trade in Stout and Porter from Britain to the Baltic regions. The English company Courage (used to?) produce(d) a "Russian Imperial Stout" which was stronger than ordinary Stout. traditionally, Baltic Porters exported from Britain/Ireland were allowed to ferment and mature during the voyage and were therefore a lot stronger at the other end.
As to the original poster... Yes, I'm a Porter fan.
