On JOHO, a bit of  a pushback to Scott Rosenberg's dismal forecast:

I do agree that it'll take a long time for corporate public blogging to spread beyond easy industries, such as high tech. But, I think it'll happen faster than Scott does. First, internal blogging will happen relatively quickly because it's a great way for employees to build their reputations, a motive as powerful as the urge not to piss off your boss. Those internal blogs will go onto the extranet and eventually some will make it onto the Internet.

Second, the first public blogs we're likely to see outside of the sw industry will be more like the Dean blog than anything else: They'll be always upbeat but still lively, full of voice, and worth reading by enthusiasts.

[Note: I have never been right with a single prediction.]
