Next time I find myself with a few free hours, I know what to do:  Take a Bayesian spam filter and modify it to do away with the following families of blog posts (which comprise 80% of my daily weblog intake):

1.   I just installed [Whidbey / Longhorn / Whatever] and it rocks!

2.  [name]  [ says / on to something / points out / links to / announces  ]   [ Whatever ]

3.  I just saw the [ Matrix / LOTR / Whatever ] and it [ sucks / rocks ]

4. Anything with the words “DON“ and “BOX“ in the same sentence (except for his blog, of course)

But really, has anyone considered a mechanism for filtering blogs?  I would love a “bool FilterPost(xmlElement Item)” pluggable interface for SharpReader ... <hint hint>
