Two bad examples of online PR are circulating.
One was a crude attempt to contribute a guest article to Mitch Kapor’s respected blog, an offer which went to several other opinion formers. Thanks to G2Blog for the link. Dan Gillmor offers a calm perspective on this, as ever.
The other was the PR attempt to promote a band by posing as a nine-year-old fan, recorded in Media Guardian. Thanks to PR Opinions for this.
