Very knowledgeable people are hard to come by and we are very thankful to have a few on this board. They are enthusists of our vehicles. Most of their knowledge has come from research, experiementing, and attempting to perform something no one ever has. Most of them will gladly share their experience and knowledge for free.
When someone asks a good question, such as "is a CAI going to raise boost/detonate my engine/improve gas milage", these people will expunge their knowledge for all to see. But they may only do it two or three times. They get tired of repeating themselves over and over.
Then you get the "hearsay"ers. These are people that know only based on what they have heard here, and have no experience with the topic at hand. These are the people that will replace a guru when he/she gets tired of answering the same questions over and over. However, the hearsay-ers are only 90% right 80% of the time. That's when bad knowledge starts getting spread about the forums.
If everybody searched (and knew how to search) prior to posting, there would be very few topics on the searched subject, but it would be very easy to find the in-depth answer given by a very knowledgable person with first hand experience. If you just post up a question that has been asked 100 times, you will get over 100 results when you searched, with answers either bad, non-detailed info or answers saying "seach noob". Doesn't help anyone. Finding the good info is like finding a needle in a haystack at this point. I've seen this happen to other forums. It gets bad real quick.
To your statement about working at a service industry. Okay, you said "working" as in getting paid. IT'S YOUR FREAKING JOB. These guys on here get no money, no fame, just pleasure at helping out other individuals with similar interests. Don't piss them off, I need them here as much as anyone else.
No one is here to hold your hand or to do things for you. Take a little ownership and man up.
