Following eight straight weeks of profiling CEOs who've done a poor job, the time has officially come for you and other members of The Motley Fool community to decide who is the worst CEO in 2012.

The methodology behind the voting is simple. Similar to an NCAA-style basketball bracket, the eight CEOs will be pitted into four match-ups that the community will have one week to vote on. Next week we'll release the results of the previous week's voting, and the remaining four CEOs will again be bracketed for voting. Voting will continue over the next couple of weeks until we have a winner, which will be unveiled at the beginning of December.

As you can see, the ball really is in your court and you do have a say in who merits the title of The Motley Fool community's worst CEO of the year. Below the voting bracket I've included a quick synopsis of the match-up; however, I encourage you to revisit the nomination article for a more complete explanation of why that particular CEO was nominated for this dubious award.

The tech wrecks: Facebook (NASDAQ:FB) vs. Zynga (NASDAQ:ZNGA)
This match-up pits two brutally intertwined companies against each other, with Facebook's Mark Zuckerberg facing off against Zynga's Mark Pincus. Under Zuckerberg, Facebook shareholders have seen half of their investment evaporate following a botched IPO. Not only that, but Facebook has yet to truly harness the value of its 100-million-plus mobile-only users. Zynga, on the other hand, has been dealing with an executive exodus as growth has slowed, all while top executives dumped a hefty amount of their holdings just months before Zygna's large tumble. Which tech wreck has more to do with the actions of its CEO? You tell us! Cast your vote below.
