Who uses feed aggregator services?
Is there anyone out there that actually uses the services supplied by online companies intending to provide products that allow you to “mashup and personalize RSS feeds”? Read/WriteWeb 
today talks about the mSpoke launch of FeedHub and how it creates “individualized RSS Feeds that aim to filter relevant posts from a set of feed sources.
Now my question here is why would you add the feed from a source and then subjectively filter out all but (I’m assuming) tag related posts that you are interested in? If you decided that Acme.com is an interesting site and you’d like to get regularly updated on what they have to say, why would you filter out all but their posts on goobers? (Or whatever, you get the drift, yes?)
I’ve tried using the Google reader shared RSS feeds, and find that hard to keep up with, though I am very appreciative of Robert Scoble for the shared feed that he maintains. Just wondering if anyone actually uses these other personalized services and if your feed reading experience is better or worse as a result.
