So Cisco is buying WebEx in a $3.2 Billion deal. As well as providing Cisco with a strong foothold in the (primarily) SMB conferencing space, there's also some consensus that the move is part of a broader strategy to compete with Microsoft's SharePoint in the collaboration arena, leveraging WebEx's MediaTone network.

While I agree that the acquisition is likely a smart move on Cisco's part I'm not sure that expensive and proprietary collaboration products are going to win out against the faster development cycles and better focus on "killer features" of open source products. I'm also continually frustrated by the WebEx user experience and I think we're in a transitional phase, in which WebEx has been successful by virtue of early entry and innovation, but will struggle to respond to expectations of a smoother, more intuitive web conferencing experience.
