Ars Technica's Infinite Loop section is very good in my experience, they don't tend to do rumor as much and their coverage is usually good and informed.

appleinsider's quality varies a lot and it has lots of terrible writers who really don't know jack (Prince McLean for instance, really should quit the internet altogether), and the 9to5 network is just garbage all around, with 9to5mac being the Apple-scenting of that garbage.

A lot of it is very US-centric and some of the 'rumours' aren't very news-worthy (the numerous stories on dock connectors for the iPad 3 come to mind) but it's far more like a news site that works mostly on facts (well, as close to facts as rumours can come) than mere speculation and conjecture. Arn, the guy who runs it, is an MD which might explain the difference to an extent.

1. What's an MD? A doctor of medicine, as my dictionary suggests?

2. There's certainly a lot more personality shining through the posts of Jordan Golson. Just an observation.

Keep up the good work!
