Nice setup Paddy and way to illustrate how it works
The thing about RSS is that it may seem difficult to understand at the moment, but the more we encounter it, the more we take notice of it and the more we learn about it, without really knowing it
The great thing is that you can wake up tomorrow and ie. 3 people may have subscribed to your Photo Blog, because they like your photos and learn from them. The system people use to subscribe to the Live RSS Feeds doesn't really matter, the point is that the blog owner gets as much exposure as possible in a fun and rewarding way.
On a friendly level people can share each others Live Feeds from their website, as you illustrated so perfectly, and this way support each other to get even more exposure (almost like partner sites).
I forgot to mention that people using the Firefox webbrowser, can subscribe to Live Feeds just by clicking the RSS icon in the address bar. This will automatically add the lastest headlines from your photo blog as a dropdown bookmark menu.
RSS may seem overwhelming at first, but in time I am sure many of us can't live without them, as we can get the exact news we want and when we want them.
