I hope others will (at least in Southern California) will find this useful and not just shameless self-promotion. I wish I had thought about posting to the forum before the actual meeting was held.
There more than enough public information out there to begin discussing webOS development, So I've decided to start before the pre is released or the SDK is made public.
Next developer meetup is June 14th: Topic HTML5 and webOS data storage.
Next user meetup planned is getting together day 1 of pre sales in front of main OC Sprint store.
