Forums are still one of the best sources for narrow topic specific discussion. I frequent several (advrider.com being the biggest) and the topic divisions keep off-topic discussion to a minimum.
advrider.com ++. Really is great for adventure motorcycle riding. If you just pay attention to popular TV you'd think you have to be some sort of film star to ride around the world on your motorbike. Then you read some of the Ride Reports there and go "Holy hell! Lots of people are doing it"
