You can submit questions about Chrome Apps at the same location above in advance too. If you are not able to watch it live this morning, I encourage you to check it out later. For online discussion during the session, you can join this Google+ event too:
Google Developer Group Silicon Valley meets on the first Wednesday of the month at the GooglePlex in Mountain View. Our meetings will always be free and open to the general public. However, we may have to limit attendance based on interest and the size of our meeting space. So, early RSVPs on this meetup group are encouraged to ensure your spot at upcoming meetings. Please see the "About" page for more information.
