What are the odds that a fellow cyclist you see around town has been to bikeforums.net? If you look at the number of views and active members on the boards, it is less than a few hundred. But they are hundreds of thousands cyclist out there. So does this mean that 99.9% of cyclists don't have a clue about the wealth of information that is available in this forum? Without this forum I would have no idea what bike to buy, lights to get, vehicular cycling techniques, and lots of other lifesaving things.
It's kind of shocking that the vast majority of cyclists just rely on their LBS or their own instincts. I suppose some do consult magazines.
