Boring isn't it. I don't socialise much these days with anyone in the industry as it is all the same discussions and crap.
Here (of course) and Pro mobile Conference is the only one I really get a lot from now, but its always beneficial to keep an eye out for trends as i don't want to end up like a blinkered dinosaur DJ, like the roadshow ("CD's will never be replaced") type people when i started.
I find the HDA events and Facebook chat excellent as it has some of the best DJ's in the UK so we can get some great discussions going and not mull over speaker combinations, pricing and whether you like scrims or not
