Background: Management strategy consulting professional David Dalka, Florian Hollender, and other management consultants are using Twitter. Ford Harding, world-renowed author and expert on sales (e.g., for consultants and other professional services folks), also has two very recent posts on using LinkedIn and Twitter as part of the business development and sales process.
Based on that context, I've started an account to get hands-on experience with Twitter. I think my home page is here. I can't stand to use instant messaging (although I do use it), so I'm not sure a federated "blurting"-thing is going to stick with me. That said, I'm willing to see whether carpal tunnel or Twitter wins out. I am also interested in developing my thoughts on both how Twitter communities form and how businesses might capitalize on Twitter.
