I think the RSS is just a beginning. Google Reader is like a custom webpage with all the information what I am interested in.

The only thing what I miss is the commenting, I don't want to visit the website just to read and write comments.

Some ideas in this field: - in each rss entry there should be a link to the RSS of the comments. - RSS readers should display them inline. - xml-rpc for blog commenting: http://www.webpronews.com/blogtalk/2007/02/20/xml-rpc-for-blog-comments - each comment should contain the possibility to write a reply (with the help of xml-rpc + a small form) - or the whole thing can be implemented on an email or IM base

Thought: Arrington has been touting SSE for over a year, and still, no one has built anything compelling with it:

certainly, the first thing one could do with this is create blog software that allows you to submit comments via SSE. There are a lot of great ideas surrounding bi-directional RSS, I'm surprised no one has done anything with them.

I'm probably going against the grain here, but I think adding more attributes to RSS is a mistake. It's supposed to be about simple syndication. In the bank account example, rss simply isn't suitable and trying to make it suitable is a hack. How about using RSS to notify a customer of an event, but have the actual content of the event stored somewhere else?

In other words, use RSS as a notification service, and have the link attribute point to somewhere that contains the proprietary format. So, anyone can be notified of the event, if you want to get more details, use an adapter that's suitable for reading that particular format.

that's not a bad idea!

you know, the more I think about it the more I like it. Maybe I should apply to YC with this idea for the winter round?

Even without extending RSS (which I think is a good idea), there is still a lot of potential in "remixing" existing feeds to personal tastes.

Pipes is one way, SeekSift.com (my company's service) is another, but I don't think anyone's got it quite right yet.

I read this through my RSS feed, but the site seems to be down... Interesting analysis of the limitations of RSS and how possible extensions could make it more powerful. [site back up now]
