Findory misfeature: unknown blogs/RSS feeds

[http://dummy.us.eu.org/robert]

I like how you can add any arbitrary feed to one's favorites in Findory.
What I don't understand is why those articles are ranked and included in
my blogs page.  It seems like you could by using some sort of Bayesian
thing.  The aggregator sux0r was attempting to do this.  (I can no longer
find its home page.)  The Bayesian thing could apply to only "novel" feeds
which Findory doesn't already know about and keep your collaborative
filtering for feeds which Findory already knows about.

Just an idea to make Findory even better.
