Tony, it may be useful to embed the videos in the post rather than have readers continually leaving the site to watch them and returning to find the next one.
For those not familiar with this you achieve this by entering the youtube video id inside youtube tags like this:
the youtube video ID is the bit that appears after the = in the URL (the bit after the last / if the url has no = and looks like: http://www.youtube.com/v/EnTf8AA_ZcQ
if you can't remember the tag then the little youtube icon (red black and white for those with failing eyesight!) on the right hand side of the toolbar in the post editior will put the tags in for you.
