Attention, b2b marketers and agencies: Show us your best and most innovative social media marketing programs. Our editorial team will choose the best submissions and recognize them in February on BtoBonline.com, in the March issue of BtoB and at an awards ceremony at the Digital Edge Live conference in San Francisco in March. We're currently accepting entries in the following categories: Best use of Facebook, best use of Twitter, best use of LinkedIn, best use of Pinterest, best use of mobile, best viral video, best corporate blog, best closed community and best social media integrated campaign (tech and nontech). Entries are due Wednesday, Dec. 19. Campaigns must have debuted no earlier than February 2012; we will not consider campaigns entered last year. In addition, our readers will have the opportunity to vote online for their favorite entries from a tech and nontech company, and we'll reveal their People's Choice winners at the awards ceremony.
