Many software development teams struggle to get the attention they need because of the way their communication is managed. Having tools to enable the team to involve the right people at the right time makes a huge impact.
Having the right feedback can make the difference between a projects success and failure. So its great to see the tools developers rely on are adopting these social tools in a meaningful way, without just recreating Facebook. The end goal should be powerful tools that easily allow the whole team to reach the whole organisation collaborate effectively.
