Clarity is always a good thing. So much stuff gets thrown under a subculture label that it's important to differentiate between the related but distinct pieces. Hell, I found this forum looking for something entirely unrelated to anything that happens here, that somebody else called "biopunk".
I know what you mean and hope you don't see this as a bad thing. Biopunk to me is something far bigger than a subgenre of science fiction for people bored with steampunk. If that would be all it was then fuck it. Seriously.
But then one would have to find another name for the culture surrounding ubiquitous synthetic biology.
To me what's happening in biology brings the same awe that futurists felt for speed a hundred years ago. I know I'm not the only one feeling it, and I haven't found a better name for it than biopunk.
If biopunk is anything it's an expression of this awe. It's an umbrella, a forum.
