There's been a bit of debate lately amongst a few Australian bloggers about how Twitter is viewed by marketers as just another place where they must impose themselves, to shout their message. Not a damned consideration that we might not want it to be a commercial space, but instead would prefer it to be a social space.<p>(As the blogger Stilgherrian notes below, there are boundaries, within which, commercial action in social networks might be tolerated.
