2011 was a busy year, so I wasn’t able to keep up to speed with all of the Ted Talks as they were released. Today I decided to look back at the most watched TED Talks uploaded in 2011, as a quick way to catch up on the best. Although I know the most popular doesn’t always mean the best quality, it felt like a good enough proxy for me!

Here’s the list I found, if you’d like to catch up on some great talks too:

10. Kevin Slavin: How algorithms shape our world (230k)

9. Ron Gutman: The hidden power of smiling (243k)

8. Terry Moore: How to tie your shoes (284k)

7. Salman Khan: Let’s use video to reinvent education (293k)

6. Sebastian Thrun: Google’s driverless car (297k)

5. Alexander Tsiaras: Conception to birth — visualized (334k)

4.Marco Tempest: The magic of truth and lies (and iPods)

3. Eli Pariser: Beware online “filter bubbles” (508k)

2. Sarah Kay: If I should have a daughter … (557k)

She recently released this poem as a hardback book too.
