O'Reilly webcasts

Not sure how I'd missed this, but amongst the events that O'Reilly put on are a lot of free webcasts. I've "attended" a couple in the last few weeks and they've both been good quality with a reasonably interactive group chat facility. So that I don't miss out on any more, I've created a simple yahoo pipe that checks the events page RSS feed, and tells me of those which are webcasts. I've simply subscribed to my yahoo pipes RSS feed and can then pick which ones I want to "attend"
