Not "again" on Mac Dev though. If you've already read a similar article somewhere else, that's great. But we don't have any coverage of WebKit in our archives, and I think it's important to cover. Since we publish 2-3 original features a week, I think the odds are good there'll be something more to your tastes soon.
As for O'Reilly's "quality has done nothing but go down," you are way out of line. If you look at the recent Panther books we've published, they are top notch and comprehensive. Our Mac OS X Conference is a one of a kind event and has received excellent feedback from attendees.
Mac DevCenter is O'Reilly's effort to provide free Mac information, news, weblogs, and commentary to those interested in developing for the platform, want to try their hand at developing, or enjoy a community with others who have similar interests.
If the content on this site doesn't do it for you. Fine, That's fair. We can't be everything to everyone. There are lots of good things on the Web that I'm sure are better suited to your tastes.
But don't come to my house and insult my family just because you don't like what's being served.
