The site I use most heavily for WordPress news these days is http://wproll.com/. I add new sites to my feed whenever anything good shows up there. That does become somewhat of a firehose though, so perhaps not suitable for those who aren't hard core WordPress junkies looking to trawl through as much content as possible. It's also not a generator of content, but with the huge number of blogs out there about WordPress, this doesn't seem to be much of a problem.

I wrote an article about wproll.com (and other WordPress news sites) not long ago too ... http://wprealm.com/blog/wp-roll-got-launched-today/
