In a time of widespread economic downturn, a number of companies powering a new form of communication are bulking up their teams with new staff. Twitter, its leading open source competitor Laconi.ca and the high-profile enterprise service Yammer have all made new hires or announced hires coming in the past week. We're tracking hires in this sector over on our new site, Jobwire.

This growth makes sense given the rush of new users these companies must be experiencing. It's not just growing hype, either. The combination of collaboration, intelligence gathering and ease of use make micro-messaging or micro-blogging a compelling addition to millions of peoples' work and personal lives.
