Please join us on May 1st for a Seattle Force.com Developer meetup.
The company I work for recently released a Salesforce1 mobile app on the AppExchange and I'll be giving a presentation tentatively titled "Everything You Ever Wanted to Know About Salesforce1 Development....sort of"
I'll be discussing all the pros, cons, and gotchas when it comes to Salesforce1 development. There should also be some time for networking and meeting new people.
LeeAnne Templeman (@leeanndroid) a Developer Evangelist from salesforce.com will also be our guest at this meetup so come say hello.
