I'm down with the idea but can't help but think "Why would i want to listen to talk about Swift from a bunch of guys that think Obj is such hot shit they made it their doman?" Domains are cheap. If you really want to promote swift, do so on a swift centric site not one that makes me think you think of it as some side thing that isn't nearly as important as that great Obj-c
And Yes, I'm actually someone who would appreciate and benefit from these talks. Not sure $9 a month worth though.
