This is not true, especially around here. In general, you will find (the knowledgeable) people in this forum will be glad to help you out and spread the knowledge, IF you do three things:
1. Realize that this is not something you can learn with just a few responses, and get the hang of in just a few days, weeks, or even months. It's an art, a craft, and also a science. You will always be learning.
2. Ask specific questions, not vague or all encompassing questions. This was worse than the legendary "how do mix drums?" question. This was more like "how do everything?"
3. Show that you are willing to help yourself. Don't be lazy and expect people to just drop what they are doing and take you by the hand and explain everything. Teachers at school get paid for this. We around here don't. Put some work into it yourself. Research. There are good tools at your disposal these days (as I put in my first post). Then come back with good, intelligent questions that show you put some thought and time into it. In general, people are willing to help those that are willing to help themselves.
You must also learn to recognize that some people are too new to things and it's really a case of the blind leading the blind. While I can appreciate their enthusiasm to help out with something they may have just learned, sometimes it's to be taken with a grain of salt. When you're new to things, you tend to think general rules of thumb are cut and dry. But once you get more experience, you'll realize that isn't always the case.
Very few people around here are guarding secret knowledge that they're not willing to share. If you follow these three advices, I can almost guarantee you'll get help around here.
