RSS feed issues

Hi

My Blog is at Tales from over the Horizon

Could someone who knows anything about RSS try to use my RSS and see if it works?
It gives me an error and says ‘This XML file does not appear to have any style information associated with it. The document tree is shown below.’

But I have heard that RSS feeds are not supposed to be accessed in standard browsers and so the browser is giving me the issue. I have never used RSS so have no idea of how to check; it would be great if someone here could.
Thanks
