Helpful or not, he needs to open up his stuff to let the community help as well. As it stands right now, he's just hit hording because it's beneficial to him. That may be fine right now, but it'll come back to haunt him later on.

Of course, if he doesn't want to release his info, it's really not that much of an effort to recreate all his stuff (it's open information anyways) and improve it greatly on an open wiki where everyone can contribute. So I guess the question is up to him. Give freely of what you have and be loved for what you've done, or horde it and be bypassed and ultimately hated for what you did. So in the long run it's better to give than to horde.

But enough preaching to the choir, it's time to get back to the topic.
