The San Francisco Chronicle has published their take on the year’s top 10 Web viral videos.

They don’t explain their criteria – but it’s an interesting list:

• Tina Fey As Sarah Palin: Not only was Fey’s impression of the Alaskan governor arguably the seminal pop culture event of the year, it also represented a turning point in the paradigm between TV and the Web. More people watched Fey’s sketches on NBC.com and Hulu.com than on television.
• The Real Palin: Though Fey’s many parodies of Sen. John McCain’s running mate set the Internet on fire, the real McCoy gave her a run for her money. 
• Christian the Lion
• Yes We Can
• Dr. Horrible’s Sing-Along Blog
• Paris Hilton Responds to McCain Ad
• Sarah Silverman and Matt Damon
• Puppy Cam
• Frozen Grand Central
• Late-night Hosts Brawl
