I will miss a few, but here's what I pick and choose from:
Posters: anybody that has an opinion and adds info to why they have that opinion. In particular, ZWK, Zyphros, Biabreakable, menobrown, EBF, JohnnyU, Faust to name a few. Ignore - anybody who shouts loudly but brings zero info to support opinion. The shark pool behavior has been much better over the last year (thx!)
Online content (twitter, websites): FBG, The Shark Pool forum, Matt Waldman, Nick Whalen, Heath Cummings (cbssports.com)
Dynasty rankings: fantasypros, keeptradecut.com (updates frequently), Mike Clay (ESPN.com), dynasty101, dynasty trade calculator (updates frequently), sites posted by Faust.
Podcasts: Locked on (Matt and Ryan), Destination Devy (Ray Garvin), Saturday2Sunday, dynasty trade calculator (Hurley and Izzy), Harrisfootball (Mon and Tu film review in season, film futures), FBG dynasty and on the couch, late round (JJ Zacharison)
Dynasty Content: I currently subscribe to FBG, if I were to switch I would look at DLF, dynasty nerds
