Many of us work in environments where we have individuals that are highly intelligent, creative, and inquisitive. Bouncing ideas off of these people would not only help you better handle the tasks that are set before you, it may also clue them into different ways of looking at problems, and help them handle task better. Unfortunately, the people within your organization that you could benefit the most from having these "water cooler" discussions with, may be in different offices, or even in different countries. E-mail just doesn't give you the ability to toss out an idea to a community, and see if someone picks it up and tosses a suggestion back. Imagine what would happen the first time you sent out one of those infamous "ALL EMPLOYEE" e-mails. The other possibility is to try to revive "instant messaging" within the enterprise, but I think that is something that gives every technology leader within an organization a twitching eye.
Having an MicroBlogging resource within the enterprise allows you to start building these relationships without overburdening the email system. It also allows you to throw things out there like links to a good article you just read, or to a competitors website with a comment of "can't we do something like this here?" Some of the messages will never be answered, but some will. And, answered by someone that you may not have ever had the chance to work with before. Breaking down barriers within the organization, and allowing the ability to really play off the wealth of knowledge that is contained within the organization.
Of course, there will be drawbacks to MicroBlogging - there's always someone that decides that it is the perfect place to talk about the concert they went to last night, or how there are cookies in the break room. But, to be honest, even these things are not all that bad. IBM has had these Web 2.0 resource internally for over a year now, and they are encouraging any type of communications, even personal activity discussion. The thought there is that people will better know other workers and feel that there is a true community within the organization.
We all hear that communications is essential to a well-run workforce. But, most organizations haven't really evolved past the e-mail phase of electronic communications. MicroBlogging within the enterprise can be the next step toward enabling employees to communicate without overloading either the email system, or each other. I look forward to testing out Jaiku when it is released as open source.
