For some of us, it has been awhile, but I still remember how I wound up at bikeforums.net. In the summer of 2003, i had just started riding and was looking to learn. My other hobbies had taught me that in order to learn about them you needed to type in the word "forum" to learn something on the internet.
To learn about Home Theater I searched for home theater forums, home improvement...home improvement forums etc.
So I typed in bike forums. And the rest is history. How did you get here?
