I just read a great biography on the actor, Peter Sellers called Mr. Strangelove. In reading about his acting greatness in playing multiple roles in the same film, I thought that this is similar to the challenge I have in managing multiple Twitter accounts. I was having a hard time keeping track of who I was talking as and at times I sent the wrong message not realizing which account I was logged into at that time. I can make you a bit manic depressive to say the least, quite like Peter Sellers.
Currently I have four Twitter accounts to manage. I have a personal account @bmcd67, two corporate accounts for Zencos @zencos and Site Dynamics @sidyn and one for the Triangle Chapter of the American Marketing Association @triangleama. I do not post everything on the corporate and AMA accounts as I have other staff/volunteers that assist with content and administration. But I would say that I am the “majority shareholder” on these accounts.
