You will get an RSS Url of the type you want only when you deploy it on development server of your site or company. Right now the feed is on your local machine.... so it will give you a url of type
http://localhost/blog/syndication.axd ..... But when you will deploy it on the development server of you comapny you will get the desired url.....
Eg: you company Name is say ... restaurant.com.. then after you deploy the blogengine code on the devlopment server you will get a link of type
So now if you have to check working of your feeds , you will have to download the RSS Readers in the machine and then add the url of localhost.... and they will work fine... You should search for only downloadable RSS readers and store them in your machine
and add trhe url... you will see your feeds there.....Thats the only way you can see your feeds now.
In order to run your feeds with online RSS Readers like google reader etc you need to put the code on development server and pass that url.....
Hope this is clear....
