This is my take on the matter and partially posted on a previous thread. I could care less myself about anyone entering the business. Nothing will stop someone who is determined and if you feel that threatened by beginners, then you better step up your game. This industry has no protection and it's a free country still. The majority here had to start somewhere, even I did. I bought a book and read it. Things are different today, where's that magic easy button?
However, if somebody in my town comes in and ask me to help them start a competing business, well you can guess what my colorful response is going to be.
Everyone here may as well get use to it. Even if non professionals don't happen to find this site, there will always be a constant influx of people trying to get in this business, with or without our help. There's no stopping it. It's technologies fault for making it so easy.
I have contributed a crap load to this site and don't mind helping legitimate professionals. I can tell who is not in this business to earn a living and I simply choose not to answer and help any of those post. Most of the time I try to be helpful and not an ass, but sometimes I digress and say something I might not have ought to, but hey, I'm human and have the occasional off day too. Get over it. What's that childhood saying about sticks and stones??
Part of the problem I see here is all the PC (political correctness) crap lately. I'm not one to be overly sensitive to everyone's emotional vulnerabilities. I see it all the time with design critiques. If you can't stand the heat, then get out of the kitchen. If you want to be in this business then you better have thick skin. Some are better at sugar coating their responses, I tend to suck in that area. My time is valuable and if I'm giving it away to help somebody, don't expect to get it with a smile on my face.
I think Signs 101 should consider dropping the rules about being professionals and let everybody and their relatives come here to learn. Just because they don't register, doesn't mean they don't lurk. Just look at the bottom and see how many guests are here compared to members. It's not like they can hurt this industry anyway. It's already in the toilet as far as I'm concerned. If you're good, you will survive in this business. If not, then you'll be looking at the next easy get rich quick business opportunity.
