This is the subhead for the blog post

Congratulations to Danny Sullivan, Greg Sterling, Marc Poirier, and Mona Elesseily, the Final Four of the 2013 Most Influential SEM Tournament!

All four contenders are making their first semifinal appearance, and the matchups have some subplots: Sullivan vs. Sterling is a showdown of Third Door Media stalwarts, and Acquisio’s Poirier and Page Zero Media’s Elesseily are going head-to-head for the Canadian vote.

Voting runs through 12 p.m. PT on Friday. Kudos and best wishes to the worthy final four!
