Yes, you have dreamt of it and Google did it. Google has launched Google Reader a RSS reader on the web. It's Ajax-based... For example, you can type "j" to go to the next article or "k" for the previous one. Nothing special for a rich client but pretty new for a web-based GUI.

Of course, do not forget to type "Baccou Bonneville" and to subscribe to Baccou Bonneville Blog RSS feed. Google is clearly making a clever use of Google Sitemaps (it's because our blog is registered using a sitemap that you can retreive it in Google Reader).
