Wow. Run, don’t walk to your nearest browser, and start catching up on
David Brin’s
weblog. I’m a huge fan of his science fiction, his nonfiction works (I try to re-read The Transparent Society about once a year), and his talks (see IT Conversations).

Now I’ve found his blog (which I can’t believe I haven’t seen
before). Outstanding discussion of science, future trends, modernism,
and…well…tons of other cool stuff (aren’t I the descriptive
one today? *grin*). HIGHLY recommended.
