Step 1 get offline and 'out there'
Seriously this has been tried, it's called a dating service/matchmaker, sure not world-wide, but the # of ppl relying on dating services is minor compared to the clubbers and bar-hopper type scene....I have done both and I prefer the non-invasive dating services like AOL and Yahoo....you see their pic, a little about them, you contact them and check out if they are a 'fun' person. Risk a date and see if that pic was from 10 years and 50 lbs ago....bar/clubs work well for short term things as I have found that world addictive (it's always easy sex if you have half a backbone).
I got into some 20-30 something social scenes too and those almost always equal at least a night in bed, but only a few real connections.
I have found most people's inability to meet people has to do with them not even being in places to meet them, and when they are they don't mingle.
My wife is nice and cool, however, way different than me as far as wildness and reckless abandon

, but sometimes I really miss the whole animalistic club scene.
