The document discusses microblogging and its potential uses and alternatives. It debunks myths about microblogging being just for broadcasting and instead emphasizes it is for conversation. It explores using microblogging both for joining wider public conversations through services like Twitter or for internal company conversations through hosted or self-hosted solutions. Questions are asked about why a company would join public or start internal conversations and benefits are discussed like knowledge sharing, collaboration and marketing. Alternatives like Yammer and others are mentioned and important factors to evaluate are listed. The document considers whether organizations are ready for the genuine conversations microblogging enables rather than just new ways to communicate downwards.
