Ever sent someone a YouTube link and informed them the certain section of content you want them to view is about a minute and a half in?

Well now you can send a link and append the following to the end if, for example, you want to go 1 minute and 45 seconds in:

#t=1m45s

where m is the minute and s is the second

So, whereas normally you'd send a link such as:

http://www.youtube.com/watch?v=SKgCXWGM3wY

and say "watch this for the greatest free kick you're ever likely to see, but if you don't want to watch highlights of a great game then spin on to about 4m40", you can now just send the following link:

Personally I think this is a great technique and now you think about it you wonder why it took so long to come about in the first place!
