The trend of Twitter

Every few days I get an email from a friend, or business I’ve done business with in the past announcing that they’ve signed up with Twitter.  I get “invitations to follow me on Twitter” up to my eyeballs!  I understand the concept behind twitter; it is a way for people to “announce” to “whoever is out there” in their “fan base” what they are doing at any given moment.  Personally I’m thinking that I don’t have that many friends or fans out there for me to think that anyone would care to know what I’m doing at any given moment – with the possible exception of my mother, and maybe my ex-wife!  I think it’s all well and good, but getting emails suggesting that I visit VistaPrint Twitter is something that I just really don’t understand!  I think that this is a social network that is not going to last very long in regards to promoting business.
