If you read me regularly, you know that I have a major pet peeve around unoptimized (and often dysfunctional) mobile experiences. So often mobile is treated an extension of the web experience and that results in broken mobile experiences... and since so much of our content consumption is on mobile devices, the lack of attention to the mobile experience is both frustrating and foolish. Great example here from the NBA (who I have had lots of social advice for!):

The NBA has 3,000,000+ Twitter followers.

40% of Twitter's users access the service via mobile (not the web).

The NBA tweets a link to the newest pair of Nike Air Jordan 8.0 shoes:

Great promotion right? When you click on the link, the NBA Store automatically redirects all mobile traffic to a defaulted storefront / homepage. And thus the frustration: 40% of those who clicked the URL, with the hope of arriving on a specific piece of content, had to give up and exit.

Also funny, when you go the URL from your browser, you get another frustrating experience: a totally untargetted promotion (hello Canadian users!):
