Everyone has at least a couple of sites they frequent where they really only care about a subset of the news that is produced there. SpecificFeeds lets you get just the news you want by applying advanced filters to an RSS feed before it’s sent to you.
The service allows you to filter by tags, keywords or author, including or excluding whatever you would like. The downside is that delivery can only be done via email. However, for those who’d like to carve their RSS feeds with a scalpel, IFTTT and some Gmail filters could be used to redirect individual posts to an app like Feedly.
