Who’s who in the media inquiry lobby effort? A number of lobby groups furiously petitioned the federal government to scrutinise the fourth estate with a media inquiry. The Power Index examines the four key groups involved, and finds that some may have irritated more than they swayed political opinion.

Avaaz — which means “voice” in Farsi and other languages — are a global activist group specialising in mobilising online rage through petitions, which are then forwarded on to politicians. Some of their current campaigns include calling for recognition of a Palestinian state, sanctions against Syrian oil exports and efforts to save the Amazon rainforest.

They are also virulently anti-Murdoch, having become actively involved in protests against News Corp chief in the wake of the News of the World hacking scandal. — Tom Cowie (read the rest here)

The People v Alan Jones as ACMA investigates bias. Ray Finkelstein QC’s media inquiry may not pursue bias in the media, but The Power Index hears that broadcasting regulator ACMA has already got Alan Jones and 2GB in its sights. We understand that ACMA is investigating three separate complaints of bias or factual inaccuracy against Jones and another two complaints against 2GB, the station he works for.

Since the complaints were made up to six months ago, it’s likely that some or all are close to resolution. If ACMA’s findings are adverse, they will be presented to Jones and 2GB for comment, in which case, one can expect to see lawyers at six paces. We certainly don’t pretend to know what’s coming, but if ACMA does take on Jones it would be big. — Paul Barry (read the rest here)

Twitter: just another social hierarchy. Are you more likely to be ignored on social networking site Twitter if you’re not considered powerful or influential? Social media expert Julie Posetti certainly thinks so.

Posetti has noted a tendency among some Twitter users to avoid interaction with those who are not well known or lack a large band of followers — a phenomenon she’s named “uptweeting”. “My impression is that there is an emerging hierarchy on Twitter,” says Posetti, who regularly provides social media training to professional journalists. — Matthew Knott (read the rest here)
