Twitter, Facebook and other social networks have long counted on the rise in smartphone usage to help fuel their growth: that trend, however, seems to also be taking a toll on mobile carriers — specifically in the form of revenues.

Now, you can do that curation from your iPad. The company was already mobile, in the sense that stories (which are essentially timelines of content from Twitter, Facebook, YouTube, Instagram, and more) created with Storify tools could be viewed on smartphones and tablets.

Linda Bustos, the industry’s insightful and incisive queen of e-commerce, says it’s hardly surprising that e-commerce apps on Facebook have faltered: most are entirely pointless apps offering no additional value.

4 weeks, 2127 sales – 1 sale per 8 fans – and a 200% (32,810) increase in Facebook ‘Likes’. That’s what the Heinz temporary popup gift-shop on the brand’s UK Facebook page delivered in October 2011 (covered here , and here , with result reported here ), selling personalised cans of “Get Well” Soup to send to a friend. At £1.99 (approximately $3 US) per can, paid directly on Facebook, the popup shop generated just £4323 ($6900) during the 4 week campaign.
