There is no end of freeloaders who will make their way to this site. The problem is not how to prohibit their actions or presence, but rather redirect their behavior toward knowledge gathering. Give a man a fish vs. teach a man to fish, to paraphrase. Those who are unwilling to put effort in will weed themselves out by either giving up or making themselves unwelcome and bringing punitive measures upon themselves.
It all comes back to the ready availability of information. I can speak from experience to say that everything is already in place to make a successful start. The knowledge and experience is there for the taking, it just requires effort. I am an avid reader and naturally gravitate toward research rather than personal conversation, so in a way you could say I'm primed to tackle this sort of environment. But not everyone is built that way. The most valuable commodity is time, so it is understandable that any way that time can be saved toward educating new members will improve this community as a whole.
I once saw a documentary about ergonomics, and there was a portion that has stuck with me. The guy held a utilitarian stainless steel potato peeler and explained that despite the tool being capable of its purpose, it was not useable for a person with carpal tunnel syndrome. They redesigned a handle with a larger and more comfortable grip, which means that more people can use it, and everyone benefits from the new design.
I also have had the opportunity to make a series of tutorial videos relating to various data-gathering tasks I must do at work. The result meant that not only can anyone do the task because of the consolidated instructions, but I have become more efficient as a result.
There is never a time that information can't be better organized and presented. I'm intrigued by what new ideas we can discover by digging into the conversation.
Let me know how I can help.
