Have you like me noticed more and more people are using "personal" twitter accounts when posting publicly on behalf of their company?
If you build a fan base on these semi-"corporate" twitter addresses or personal? Are Twitter name rights the new "rolodex" ownership issue.
When you leave the company for greener pastures is there going to be blowback about taking your userbase with you to your next role, or is there the assumtion that this account is dead/renamed for your replacement?
Surely it makes more sense to enforce "branded" names eg @CNN_Anderson or @CNN_LarryKing etc
