It can be a positive impact for the Asian community because people here in America take in their pop culture and become familiar with their lifestyles. It is possible that the more recognition a person from the Asian community gets on YouTube the more the Asian stereotypes can go down.
timothy gave a funny outlook of asians. he includes stereotypes of asians but made it in a funny way.
I think it gives a rather slim view of Asians, and to people who don't understand Asian parents or culture themselves, might completely misinform what Asian culture is actually like.
