Personally I've found the following articles to be the most useful (in no particular order). I tend to look for value on the fringes so my bias will be towards those articles.
Russ and Mike's Top 20 Eastern/Western players per position. Good, quick blurb for each players make it useful as a launching point for further analysis.
Angus's Lockout Beneficiaries / Losers series. Very helpful for perspective and forecasting future results.
Rick Roos' Holding Court, specifically on Jimmy Howard and Pekka Rinne (I am biased since I own Howard in one league).
Steve Laidlaw's Larsson v Hedman article.
