Cutting edge blogging

I'm into the final push for my presentation, From the Margins of the Writable Web, for the Emerging Technology conference next week. I've been working on this for weeks now, but now I need you — the general public — to make sure I haven't missed any bleeding edge weblogging stuff (i.e. not warblogs or anything you'd read about in the paper). What's happening on the far-frontiers that I might have missed? If you've any ideas, please let me know via email. You'll get credit in my presentation if I use your example, of course. And I'll be posting the presentation afterwards to this site. Thanks for your help and participation, I appreciate it.
