"PubSub is about to go into its next phase and I'm separating from the company, so my email address won't work anymore. when I started PubSub, it was always the intent to build it to a certain point and then leave to do my next venture. After four years (internet years, no less), that time has come." Good luck Salim - it was a pleasure working with you at PubSub. I'm looking forward to learning more about your next venture.
