andrewgould on "RSS feed uses the old name of my blog, even though I've changed it"

I am now back using my andrewgould.wordpress blog, after leaving it unused for quite a while. I decided to check my RSS feed by pasting it into my Google Reader. It worked, but has the title of my blog as it was before, which is Andrew Gould's Images.

I registered andrewgouldsimages as a domain name with WordPress nearly a year ago, and then decided to stop using it. I then switched back to andrewgould.wordpress, and this is how I will continue it.

I cannot see anywhere in my settings, Andrew Gould's Images anymore, since I changed the blog title to AndrewGould's Photojournal. Can anyone tell me why the RSS feed has not changes to the latter name? I may have given some unnecessary background here, but wanted to make the facts clear.

Thanks,
Andrew.
