What is the problem with trolling?
The best boards I have ever used are free-for-alls among adults (none of them are autistic like me though) - plenty of hilarious trolling, but it rarely gets totally out of hand.
It saddens me that so many people view the use of humour on message boards as a sinful act of 'trolling'.
Now, perhaps this is why geeks use boards and normal people use social networking?

This isn't the type for forum for that kind of behaviour. Other forums do exist to facilitate that to a degree, like Intensity Squared for example.
Also, generalisations are no fun. I'm a geek and I use both boards and social networks.
