It used to be alright, but for some reason it seems to have become overpopulated with characters who argue primarily from their gut instinct and worry about logical consistency and related works/evidence only after the fact (i.e. razorsedge). This is not to say their contribution to this board is useless, just that when it becomes the norm the type of discussion descends into a battle of characters and not arguments, moving it farther away from the philosophical discussion intended by this board.
Then their are others who seem to have shady agendas to promote (i.e. the national socialism of Norsemaiden) and little else, which often taints the discussion, veering it off course into pointless obscurity which no decent person really wants to engage with.
How can we get intelligent people here? Well Cyth posted on here for a bit, he is currently doing a master's in philosophy as far as I know, so he is an intelligent individual who is well read and generally civil in his discussion, but he seems to be the exception and not the rule unfortunately. I honestly, don't know how to get some decent debates going again, maybe it would be best just to try another board. The GMD Social board has some alright political discussion if you can stomach V5's zealous reactionary persona and Dakryn's pseudo-conspiracy theories and constant Ron Paul fellating (not to say all the things that he talks about are conspiracy related). So maybe try that, if that's what you're looking for? Cause I doubt this ghost town of a board will suddenly begin to thrive anytime soon.
Obvious suggestion: if you don't see a topic that interests you, start your own and see where it goes.
