One of the most magnificent qualities of the Internet is that,
by bringing the world close together, it enables people who
fill one tiny corner of interest to come together, marketing
to each other, sharing ideas, and growing as a niche
community. For instance, consider antique marble collecting.
I dont know many people who collect antique marbles. But
if I do a search online, I can find dozens of sites that specialize in it, many with excellent information on their
sites, places to trade and sell my antique marbles, and tools
with which to make my own marbles.
