In his blog on influential marketing, Rohit Bhargava who works at Ogilvy has listed 15 social media trends that are changing the world of marketing.
I especially favour his No. 1 Likeonomics that shows how a Like by the right person on a Facebook page may mean more than a major campaign in print.
His No. 5 Rise of Curation is another favourite, with examples like paper.li and the iPad apps Flipboard and Zite.
No. 9 Appification of the Web is yet another interesting aspect, also described by Chris Anderson and Michael Wolff in their Wired article The Web Is Dead. Long Live the Internet.
