Not really got time to go into this in well thought out detail right now but:
He makes a few good points -
There is more to trial work than digging - there is room for the people who's input is writing the letters, talking to land managers, facilitating meetings, raising money, building websites.
Digging should be more accessable. His point:
"Nor am i comfortable with going out to a trail where i think needs work done and start doing the work myself because i know that i am unskilled or qualified in that area and anything i do will most likely make it worse."
is one that i totally understand and symathise with and until i got chance to join up with some build days i wouldn't try to make changes. Inparticular reading some threads on RB where people are kicking up a stink about someone making changes to "their" trail
Points to disagree:
we'd be as well off riding crap trails if we could all get along nicely. I don't think this is a reasonable argument because MTB is a growing sport. The people coming into the sport are not only coming in from the youth ranks of racing, they are (re)entering later in life and from numerous avenues (the FFF and i were dicussing where all the new riders are coming from and came to the conclusion that they are coming from all sorts of angles - roadies/new golf, riding with their kids, fast bushwalking, bike paths on steroids to name just a few) - if we want to keep these people coming out to ride over that first 2-3 year period of off road riding, they will need to be riding good quality well maintained trails within easy reach (45 mins drive) of capital cities, otherwise we run the risk of loosing them as they stop having fun
Something of an aside - Rotorburn (or the other one which i'd never heard of until today) are only a very small part of the MTB community. On a build day at the weekend we had several people come past and ask how they could get involved - we pointed them here and they'd never heard of it. These were not people who'd only just put knobblies on their huffies - from appearances and the discussions we had with them they are long time riders with a keen interest in keeping the quailty of our local trails, both for themselves and to encourage others to use the tracks.
Sorry for the run on sentences and other terrible grammar
