I use claws-mail for email and it comes with an RSS plugin.
It's very useful because the RSS feeds are treated like email. You can mark individual items as read, important, tagged, and so on. As well, you can use the email client's normal search features to search for text in the content. I use this feature a lot to categorise interesting topics.
The plugin (and claws) are open-source written in C++ if you are looking for ideas.
BTW, I use it to read HN. HN's RSS feed only offers topics that have been voted up (I think), so I see only worthwhile topics. Helps sorting the wheat from the chaff.
