I only recently found out about GigaOm's upcoming Net:Work conference. It's held December 9 at UCSF Mission Bay conference center. While the name of the conference is a bit ambiguous, the actual area of focus is very clear: how will we collaborate in the 21st century?
The impact of smartphones, tablet computing, social networks, Software-as-a-Service and Cloud computing is just starting. As a result, I think there are tremendous opportunities for startup companies to disrupt existing markets with more modern, lightweight applications that foster collaboration inside the company as well as with partners, vendors, consultants and customers.
