"Watching" means you're monitoring the event to decide if you want to go or not, not that you will literally be watching it from afar. If you want images of the event, you'll either have to gather them directly with your eyeballs or check Flickr shortly afterwards...
If pictures added to flickr are tagged with, in this case, upcoming:event=208895 , they will automagically show up under the "Photos" section on this page.
I concure with Joan's sentiment. While it would be great to attend the event, it would be better to stream the event and actually allow 'watching'. Particularly for those of us not in SF.
If anybody is recording the audio or video, please post a link back after the event. (e.g. Youtube, etc)
