Way, way down the list of notable items about the departure of Sun Microsystems CEO Scott McNealy and the announcement of Jonathan Schwartz as his replacement is this:  there is now at least one high-profile CEO with an active blog.  As discussed here and here, Schwartz is the author of Jonathan's Blog, which actively discusses goings-on over at Sun. 

The naming of Schwartz as CEO leads to entertaining leads such as this one in the CNN article linked to above:

"In a Hail Mary move to save the company, Sun Microsystems has just appointed a ponytailed blogger as its CEO."
