speaking engagements?

My highlight of the day: being asked to present on Web 2.0 as a teaching tool during a monthly meeting of local school technology administrators. Humbling indeed, and very cool as well! Looking forward to that...meanwhile, I've been busy planning and foraging for content for my inservice class I'll be teaching to staff at the end of this month. The topics will include blogs, podcasts, wikis, social media (aka Web 2.0). I already have a few things in mind to share, but if any of you out there know of a particularly cool site, app or tool, leave a comment and I'd be forever in your debt!
