Grazr is truly an RSS reader embedded in a blog, which is another very novel service.
Usage method:
1. First, you need an OPML file, which can be exported from the RSS reader you are currently using.
2. Place the OPML file on the web because Grazr currently does not support uploading and can only reference external addresses. Therefore, I placed my OPML file on box.net, but of course, you can also place it in your own blog space.
