Matt Cutts, who works for Google – specializing in search engine optimization issues, has written about how to to link to a specific part of a video on YouTube… I didn't know this was possible… But it is!!!

If you want to link to a specific part of a video on YouTube, you can. For example,

youtube.com/watch?v=PjDw3azfZWI#t=31m08s

Notice the “#t=31m08s” on the end of the url? That link will take you 31 minutes and 8 seconds into that video. This example takes you straight to where someone asks Eric Schmidt a question about Twitter. From there, you can listen to his answer.

Matt Cutts works for the Search Quality group in Google, specializing in search engine optimization issues. He is well known in the SEO community for enforcing the Google Webmaster Guidelines and cracking down on link spam. Cutts also advises the public on how to get better website visibility in Google and inequitably imposes, as some justifiably argue, the infamous "Google penalty" on select websites.
