I'm not a corporate blogger, or Tweeter, but thought this post has sensible advice for anyone who uses social network services in a corporate environment. It has a review of Twitter tools, tips about followers/following and advice on handling company complaints via Twitter for those who have that responsibility.
Confessions of a corporate tweeter - econsultancy.com
There are lots of articles about how brands should use Twitter. They all give good sound advice to the budding corporate tweeter: listen before you dive in, have something relevant to say, or learn from cases like Motrin or Skittles.
This is all very generic though, so let me try to give you my random insights and observations as @guyatcarphone, a corporate tweeter for Carphone Warehouse...
My employer, The Warehouse, doesn't have a formal Twitter policy other than generic corporate net use conditions. I don't use Twitter much at work although sometimes review my CAD/BIM & IT groups in TweetDeck. I found Twitters stream of information overwhelming but grouping has helped make sense of it.
I use RSS Feeds more frequently and have a similar set-up for blog/discussion groups in RSS Bandit. I have structured Work, IT and CAD/BIM related feeds in to categories (right) and dive into them as needed. They are an invaluable resource for support, training and development information.
I'm not on MySpace or Facebook (which I think is blocked) but do use LinkedIn at work. It's proven to be a useful tool for extending my network within the industry and maintaining contact with former colleagues.
Note: Carphone Warehouse is a U.K. company and has no connection to my employer. However, I found this post via a search feed I have for "Warehouse & New Zealand" as Guy Stephens is a Kiwi and mentioned N.Z. in his post.
