My experiments with new services that offer tools to mix a set of different RSS feeds into one was interesting, and the comments brought in a few more. I’ve updated the original post to include:
Feedjumbler had likely the easiest setup and mix of good output features, FrankenFeed was clean and had the coolest logo, and Aggssive is intriguing for the whole tagging business. Others worked, but took longer (e.g. entering one feed URL per form field, others choked on bad RSS.
John offered a good list where I got most of these. Wow, there’s a whole pile of these.
