I think it is extremely important to be watchful in the martial arts world. After all, there are many people who are unable to determine combat movements from high level circus tricks. In every occupation there are those who would seek to take advantage of the curious, swindling their money over a long period of time while giving them techniques that are not only questionable, but dangerous in a real situation. Phonies and conman of all sorts have almost lead the charge on spreading martial arts, seeing an opportunity to make quick money while the real practitioners have remained so secretive that they have almost disappeared entirely from the modern day map.
As the world continues to get "smarter" we weed out these conman through making blogs and videos exposing these cheap parlor tricks. But at the same time there remain many older martial arts techniques that have also been deemed as ineffective in the eyes of modern martial artists. Movements that may be a bit more complex or difficult to learn have easily been disregarded and seen as performance while everyone continues to adopt a simplistic form of boxing. In short anything that doesn't look like what we've already seen is in question.
