Well, you saved me writing a similar comment, and I like your blog too. (BTW I completely agree with your musings on what we might do with all this hardware, post-bubble. I actually started and... not quite abandoned a "sci-fi-ish short fiction" series on my own blog trying to think through those applications in my own industry.)
In my own writing it's like, I'm mostly trying to put something out in the world that I, and sometimes my friends, enjoy. The rambling is not exactly the point, but not exactly not the point either. If other like-minded people find it, great. Once somebody tipped me a thousandth of a Bitcoin or so, and that was fun too.
