Regarding the two sites linked, one is focused on the Star Trek vs. Star Wars debate, but takes the whole thing fairly seriously. They've got some kind of running feud with TF.n and Karen Traviss, the EU author and "defense specialist" pushing the idea that the Clone Army was only 3 million strong. The second is the work of an astrophysicist, and it got him hired on to write a couple of the reference books. Both are generally informed and rigorous -- sometimes moreso than the original movies, but sometimes they bring to light the cleverness of Lucas's crew that we might otherwise overlook.
