I'll give microblogging a serious thought when there are protocol standards and more than one provider is actually operating in the space. All of the open protocols are already in place for someone to trivially build a clone of twitter's basic functionality. And actually, there are a number of microblogging sites out there lying mostly derelict. The real value of twitter is not its technology, but its vibrant user activity. And you usually don't get critical user mass unless a closed system is locking them in somehow.
