Enhancing the blog

I was trying to add an RSS feed to my blog, which I was not able to do, but stumbled instead upon this new feature which lets you add videos from YouTube and Google video to your blog. I chose "Flowers" for the title, and roses, daffodils and irises for the subjects. Very odd collection of videos resulted- including a Guns n Roses video and some other things. It seems to change, so I'll keep an eye on it- maybe change my search terms to be more specific.
