BoomTown will be driving the minivan–packed with my assistant Ed, my mom, two mannequins (don’t ask), a coffee machine and lots of coffee and some very nice outfits–down to the seventh D: All Things Digital conference today, so don’t expect much in the way of blog posts from me.Thus, I hope Twitter doesn’t sell to , Yahoo (YHOO) CEO Carol Bartz and Microsoft (MSFT) CEO Steve Ballmer don’t agree to agree (until they are on the D stage next week) and Facebook’s valuation doesn’t ricochet up and down the blog-hyped scale once again.But, in that event, the rest of the well-oiled All Things Digital machine will be in full force covering tech and media news, even as we gear up for the big event next week, which will feature pretty much all the major players in the digital space.On my way to D, I will be stopping by the University of California at Santa Barbara to speak in its Tech Management Lecture Series, which is titled “The Tomorrow Makers: Change & Challenge for Entrepreneurs & Innovators.”Ah, the makers of tomorrow!
