Larry Page really got people talking last week.

The Google CEO saw a huge surge in mentions on social media platforms during the week of May 11 to May 17. He was mentioned 4,481 times, up from 1,714 mentions the week before, according to data gathered for Inc. by social intelligence company Synthesio.

Page's social buzz peaked on May 15 after he published his annual founder's letter, which outlined some of the things Google will focus on in the future, such as improved search and design and greater Internet access worldwide. The availability of Google Glass to the general public also boosted mentions of Page and his company.

As predicted, Facebook founder Mark Zuckerberg's entry into his 30s was a hot topic on social media last week. And although he didn't celebrate a birthday, Tesla CEO Elon Musk also trended during the week. The entrepreneur's social popularity was fueled by the publication of "an illustrated love letter" by Matthew Inman--the man behind the comics website The Oatmeal--to his Tesla Model S. Inman followed up the cartoon with a request for Musk to donate $8 million to help fund a Nikola Tesla museum. Musk obliged.

In the startup world, Uber saw drastic dip in social media mentions last week compared to the week prior (from 35,298 to 16,604). The downturn was surprising, since last week the car service company announced that people would be able to use the service to book private jets to the Cannes Film Festival.
