Need for an RSS Aggregator Service?

I find myself really wanting to build my own aggregator of RSS feeds.  I use Google's custom home page for my rss needs, and for the most part it works pretty well.  But I dont' want to add all the RSS feeds I like to it, just not enough room.  What I really want is one box that I have display a merged version of 10 different feeds.  These are my friends and such who only post once every few days.  It would take less space and offer an easier interface for me.  Am I alone?

I think there could be a real value in a web portal that you can send a list of feeds and it will create a custom merged feed from.  It would have its own page but also be available as a feed for whatever needs.  You can do this with Yahoo Pipes, but pipes has issues that prevent it from being as useful as it could be.  A it isn't easy to find aggregations that already exist.  B it is quite slow.  C the interface is intimidating to all but techies.  D I could go on.

So, would you use a service that for no cost would merge your feeds into one feed and output it on a friendly page and also give it to you as RSS?  Would you want to create many mini aggregations?  Would you want to share them with others, people you dont know but may share your interests?

A good example of an RSS agregator that I use all the time is FullasaGoog.  I wouldn't want or try to replace it, but rather offer that kind of functionality to people to create their own and for any kind of topic/category.
