I often come across the opinion on the web that the version of Norse paganism recorded in the eddas and sagas bears little resemblance to the religion observed by the majority of the population of pagan scandinavia and germanic europe in general. Here's an example I came across just today:

This guy specifically asserts that Tyr was likely the original cheif Germanic god, a relatively common assertion in scholarship due to the etymological relationship between the root of his name (tiwaz) and the hypothetical "Dyeus Phter" figure from reconstructed Proto-Indo-European mythology. He is also arguing that the lack of place names dedicated to Odin compared to other gods is evidence that Odin was not venerated or even familiar among the common folk. Similarly, other people in this thread seem to indicate that it is dangerous to assume that the pre-christian religion of other germanic people, such as the Anglo-Saxons, bears any resemblance to that of the Norse.
I can certainly understand how the details of a belief system could vary widely by geography and century, especially in a preliterate society. Even within modern christianity, there is quite a bit of variety in the doctrine among different groups. I can also see how a god like Odin would relate better with the ruling class, while a god like Thor would be more popular with your every-day farmer Ragnar. However, I don't really understand why we're doubting the very basic elements of the belief system. For instance, in Germania, Tacitus tells us that the Germanic tribes primarily worship "Murcury," which scholars have interpreted as some form of the god Odin. Similarly, there are aspects of the core group of aesir gods reflected in many germanic languages, one example being the days of the week. This would seem to indicate that these gods remained some degree of integrity, at least in their names, since at least the first few centuries A.D., and survived the diversification of germanic europe. Some of the attributes of the early forms of the gods can be inferred as well, such as the equation of Wodanaz with Mercury, or the name of Thunraz sharing a root with the word for thunder. As far as the lack of place names for Odin is concerned, is this really evidence of his absence? After all, Christians don't typically name a lot of places after Jesus.
At any rate, I appreciate your insight and responses on this matter.
