I guess that by now you know I like to share a good presentation or YouTube video now and then on this blog.
This one is from ESP Emma (aka MyEmma). It's on slideshare since quite some time now but anything that covers the combination of email marketing, social media (and this includes blogging too because people tend to think Twitter or Facebook only these days when you say 'social media') and all possible sharing platforms and devices, including mobile, gets here sooner or later.
