Later I also added news items to the newsletter and wanted to combine news from multiple sites. So I had to find a way to aggregate news items of RSS feeds and limit the results to those of the past week.
The solution came with Yahoo Pipes, a visual tool to aggregate, manipulate, and mashup content from around the web. With Pipes I was able to combine two feeds, filter out only those news items of last week and sort them all by date again. The result is a regular RSS feed, which can be used in Tripolis Dialogue as described previously.
