1-its really not to difficult for mw to come up materials that are intresting to me and my readers on a regular basis.  the reason it is not very hard is because i have a decent knowledge of the subjet and am very intresetd in it so i dont mind looking up stuff for it.  some of the challengs would be for a wold wide audience it would have to be in the many lanquages of the world.  i am terrible at any lanquage besides english so for that it would be a bid issue but besides that i think i would be fine.
2-a woory that people could have reding my blog may be the prices of the boards.  i dont have the prices because depending on where you buy the board or bindings  the prices may very.  i would respond to them by telling them the price on the sights i buy my snowboard gear off !
3-if i had and unlimited time and money to make my blog better i would do a few things.  first i would have the oppions on the boards from many of the pro/am riders who shred the boards.  second i would have computers that send out a 3d hollagram of the board so u can se the exact shape and details of the board.  last i would make it so every month or so thers a get together to test all the boards and bindings to see how they ride and then write reviews of them !
4-in a way blogs make thing better.  they get the word out and help many people.  for example it imformes people and gives them information on the subjest.  also it could be bad becuase many people get in fights on the internet over the stupidest things.  on a blog people can say stuuf they wouldnt say in person so in that way it also can be bad. 
5-i could see blogger helping people in the futur.  for example if people blog day to day and something extraodanry happens people in the futer could learn about it in a simple way.  also they can use it for what it is used for today, just about everything from about life to gear in sports.
