NEW YORK ( TheStreet) -- 2011 was filled with loads of blunders from CEOs of top tech companies, from botched product launches to sketchy accounting and questionable mega-scale acquisitions.

But which top exec was truly the worst?

Here's a roundup of some of the most terrible tech CEOs of the year. We'd like readers to read the following summaries and then cast their vote in the poll at the end of the story. And don't forget to leave comments if you think we left out a deserving CEO.

Reed Hastings, Netflix (NFLX - Get Report)

The once beloved Netflix committed error after error this year, pushing the stock down nearly 62%.

While just several months ago CEO Reed Hastings was viewed as a golden boy of the tech world, he's since been pushed off his pedestal after mishandling a subscription price hike and confusing consumers with plans to split up the company's DVD-by-mail and subscription businesses.

Consumers reacted angrily to the changes and the company ended the third quarter with 200,000 fewer subscriptions than expected, even after lowering its forecast by 1 million in September.

Andrew Mason, Groupon (GRPN - Get Report)

When Groupon CEO Andrew Mason first came into the public eye, he was praised for his unconventional, colorful management style.

Fast forward a year and Mason is now considered a major liability to the daily deals company.

While preparing for its IPO, which took place in early November, the company committed a series of missteps, including the adoption of accounting policies that raised concern from regulators, over-expansion and management turnover.

Shares of Groupon are down 31% since their debut, falling below their original pricing at $20 per.

Jim Balsillie and Mike Lazaridis, Reserach In Motion (RIMM)

Once the leader in the smartphone space, Research In Motion has fallen by the wayside as rivals Apple ( AAPL) and Google ( GOOG) have become dominant.

Shares of the BlackBerry maker have plummeted 68% this year after a string of dismal earnings, a half-baked launch for its PlayBook tablet and several product delays. Balsillie and Lazardis, who share the CEO responsibilities, also presided over job cuts this summer.

RIM was also beset this year by a three-day BlackBerry outage which angered customers.

Tim Armstrong, AOL (AOL)

AOL is struggling to reinvent itself from a dial-up Internet company to a world-class content company.

With shares of AOL down 40% this year, CEO Tim Armstrong hasn't found a way to boost traffic on the company's network of sites despite several high-profile acquisitions this year, including picking up The Huffington Post for $315 million and TechCrunch for a reported $25 million.

The company is also spending $40 million a quarter on its hyperlocal business, which still isn't generating any profits.

Mark Pincus, Zynga

While Zynga hasn't yet faced the wrath of the public markets -- the social gaming giant is expected to launch its IPO on the Nasdaq in the next few weeks -- CEO Mark Pincus still makes the list because of reported poor treatment of his employees.

According to the Wall Street Journal, Pincus has demanded that several early employees return portions of their stock options or be fired.

Start-ups like Zygna often use stock options as a way of luring top talent with the promise of cashing out one the company goes public.
