When I first started taking an interest in semantic web technologies, I sought out places with quality information and opinion. Too often I found there was no up-to-date 'directory' listing the thought leaders in the field. Many information outlets were associated with specific products rather than design principles or standards. That made the initial learning process painful. For the first question in `SementicOverflow` I'd like your thoughts on where the richest sources of impartial semantic web wisdom and background are to be found. Where should I go, if I'm a beginner, to best help me ascend the semantic web learning curve? What about if I've grokked the fundamentals and want to dig deeper? How do I become a semantic web ninja? ---------- UPDATE ====== The following list shows the links provided so far. Information Sites ----------------- 1. [http://www.w3.org/2000/10/swap/Primer][1] 2.
