Another challenge is when your alt culture goes mainstream, now it's just culture. The alt community has to tack deeper to the extremes to stay alt. You don't need an alt board to talk about current events (aside from conspiracy theories)
While this is true, I still experience a little of that early-exposure-to-the-Internet sense of wonder when I stumble across a community that's off the beaten path technologically. sdf.org's Gopher service was such an experience in the past couple years.
