How to make money with blogs was a hot topic during two consecutive sessions on digital media at American Business Media’s Spring Meeting Tuesday, writes BtoB Online. Joining the discussion was Ethernet inventor Bob Metcalfe and a partner of Polaris Venture Partners: "The ‘blogosphere’ throws all sorts of old patterns into disarray," he said, referring to its impact on publishing - and its revenue potential. Meanwhile Jim Spanfeller, president-CEO of Forbes.com, said the site will surpass the print edition in terms of revenue "probably in about 18 to 20 months." Forbes.com is run as a separate company within Forbes.
