I got asked to do an hour during the 24 hours of PASS that is happening on Sept 2. It's a 24 hour marathon, spanning the globe, where you'll have (I think), 24 speakers who will be broadcasting across LiveMeeting to anyone that wants to drop in for an hour. I don't have a schedule yet, and I'm not sure who else is going, but I'm slated for 10am-11am, MST, which will be 4-5pm GMT. Do the math for your own time zone.
I'm doing a new presentation, Building a Better Blog, which will be based on my experienced writing, editing, and reading lots of blogs over the last few years. I'll give you some tips and tricks of what you can do to build an impressive blog for your career along with examples of what I think are good and bad entries and formats.
