When I'm filtering around the interwebs looking for things of interest, I prefer to look for the commonalities between different approaches rather than the differences.  For instance, I figure that if I look at how an aikido guy does a particular thing and how a karate guy does a similar thing then the truth might likely be somewhere in the middle.

What is even more interesting to me is when I see suggestions of Parallel Evolution.  That is, separate practitioners from different cultures that hardly intersect - when those guys come to a similar practice or conclusion, there's probably something there!

Here is one of my current practices as an example of Parallel evolution.  Sure, there was probably some interaction between Chinese and Indian cultures, but these two groups appear to me to have come to a very similar point.
