Interesting topic. I do not feel that there is a difference in humour between Europeans n that of Americans, although I did at one time think so. I once hung out on Yahoo chat with an IRL friend who had a similar sense of humour to that of Raasy. She was misunderstood on there because, we felt at the time that most of them were Americans n thus somehow didn't get the British sense of humour. They would think she was being nasty when she wasn't being.
So to take this example n the one you've illustrated (the lounge n EADD) it shows kind of opposites in maybe Europeans don't understand the American sense of humour. So I'd suggest it's simply a case of perception. I'm trying to think of the words bare with me here being on holiday I packed my brain away n for some reason can't remember where I packed it. Group identity n "area" may have affect. For instance, the Lounge is meant to be somewhere whete people don't take themselves seriously. It's known to be humourous n "piss-taking" (don't like that word but could not think of another), people go at each other in a jokingly, non-malicious sense n it's all meant in the spirit of fun. The majority of, but not all of the members, are Americans.
Meanwhile, EADD is obviously for people from Europeans areas, although we do openly accept n welcome people from outside of these, One Thousand Words being an example. Although this is the case, the sub-forum goes with the ethos of the site - harm reduction, drug discussion with social, non-drug discussion. The difference between EADD n the other sub-forums is that it caters for Europeans but is not limited to one drug group or a few drug groups or a specific topic only, as is the case for Electronic music discussion or Other Drugs. EADD differs from the Lounge as does every sub-forum on Bluelight for reasons I have stated above. The Lounge is based on non-drug discussion n light-hearted teasing n humour.
The way in which EADD is formed, there are going to be serious discussions here whether that be drug or non drug based. Things get taking seriously because people often come here for support, for advice, for information n for company. The advice given here can often make the difference from someone taking drugs safely n someone taking them recklessly n ODing maybe even ddying. It can be the difference from someone becoming an addict or maybe (this statement is probably controversial so let me explain. Once, a few months I think, a poster made a thread here asking about Heroin. He wanted to try it n he wanted to know how he want about doing iy. Most of the members here, especially Heroin addicts, explained why taking heroin was a bad idea. This, if I remember rightly, was done in a non-patronising n non-judgemental manner. The OP decided not to try Heroin after this due to the good advice people especially those who have had negative affects from Heroin, some have had their lives ruined n are picking back the pieces of their lives.
Do you have any other exemplars to illustrate your point, other than differentiating the humour of EADD posters with posters from The Lounge? I can't speak for all Europeans but you may find that British people have a good sense of humour n some even to that of the lounge.
