I have no idea you this mean by saying that.  If I have a river of items 
flowing in a group of feeds, and I can't read all the items because 
there are too many, then what better way is there than to specify 
keywords to exclude all the items which  do not contain them ?   Now I 
don't know if that was what Ryan originally wanted, but  it's sure what 
I want.

But that assumes that it is practical to store all items flowing in 
many-many feeds in a database.  What happens when instead of  200,000 
feeds we are dealing with 200,000,000 feeds or even 200,000,000,000 
feeds.  If the AOLs and the MSNs get the knack of RSS , then we got to 
think of how this is going to scale way way beyond where we are today.

What am i missing ?
