Is there a viable replacement for Feedburner for bulk feed management?
This is a good question; I’d like to know the answer. I use Yahoo! Pipes a lot. I love the idea of Yahoo Pipes; but, lots of things on the Internet do not necessarily always perform as advertised. I would be happy to pay a reasonable amount for a premium Pipes service with better performance. I actually wish Google Reader would merge with Feedburner, just buy Yahoo Pipes, and mash them all together. ;^)
There is Superfeedr; but honestly, I haven’t been able to figure out how to use it yet. The main problem I’m having is understanding what it does and how it works from a theoretical perspective. I’ve been busting my nut for a few days trying to get Superpipes  to work properly, but without success yet.
