I've come up with a way to easily separate the RSS generated by the Rapidweaver blog page so that you can run category-specific RSS feeds (I'm working on a satirical fake news site, so I need a master "archive" and to be able to run RSS feeds like "News", "Sports", "Politics", etc.
I've been using the RW blog page as the "archive" for the site, and after I publish new stories, manually linking them to the individual pages generated by the blog, and adjusting the layout accordingly. As you can imagine, it's very labor intensive to keep updating and modifying the layout time after time, so I looked for an RSS solution.
And I finally found one through a combination of Joe Workman's RSS stacks and a Yahoo service called "Pipes"
First, I made sure my categories were enabled and defined, and that each blog post had the correct category name.
Then, you go to the yahoo pipes site, and in a nutshell, you enter the main feed, link that to a filter that you set up to either include certain categories or exclude categories, and you then link that filter to what they call the "pipe output". You then publish the "pipe" (important note: publishing it makes it visible to the public), and generate an RSS link. Copy the link and paste it into one of Joe's stacks and you're home free.
The site is very user-friendly, and they have great videos to explain how it works. You do need a Yahoo ID to use the service.
I know a couple of you out there were looking for a way to do this, and since I couldn't find an answer here earlier, I thought it was worth sharing.
