It's hard to say why some boards succeeds more than others.
I'm the new guy here, as I've only posted a few times and more to the point...I'm not a professional (Welder that is).
However, I'm no spring chicken (47) and have been around boards for a long time, seeking out advice where no one in my near proximity could offer an answer.
I'm by profession a pilot. I flew fighters in the Norwegian air force (F-16's for the most part) for a decade before I joined the civilian ranks and became a commercial airline pilot.
I'm a literate man, and love books. I'm also a practical man who set my pride in fixing things and get them to work. I try to learn as much as I can of any trade within the boundaries of my time and talent.
I used to be, and still am to a certain degree, a computer wizard. This was beyond the scope of my work (we have support and professionals running the show), but I remember from my air force days how frustrating it was waiting for some support bloke to come and fix a trivial problem that grinded our squadron to a halt.
Therefore I started studying computer programming. I became somewhat of a wizard in Windows problems and various applications we dealt with.
It was a deed of necessity, more than one of passion.
I did, however, develop a curiosity beyond the needs of the squadron at the time, and started looking outwards.
That's how I came in contact with a lot of computer programming forums, and ended up as a member of quite a lot of them. The one I got especially attached to was WDF (webdesignfoums.net, which has been sold a couple of times and changed owners after that), who dealt with programming web servers.
After beeing a member for a few years I was promoted to moderator. Point being that you get a kind of community feeling after a while. You get new friends sharing your interest, and it becomes a whole new social sphere you can interact within.
I actually met one of my moderator friends when I took my whole family to Miami on vacation in 2003.
That was a thrill!!
We had become friends after years of writing and moderating the same forum, and hit it off immediately when we first met in flesh and blood. I felt I knew the guy already, and I wasn't wrong. He was just as I imagined after talking through numerous post throughout a couple of years.
The reason i ended up on that forum (I had been through numerous in those days), was the fact of their friendly and including tone. The board was heavily moderated to weed out spam and obnoxious posts, and that made it stick out. That kind of politeness and all inclusiveness, made me stick to the board.
There were many members in different countries who tried to start their own boards and failed. I can't really say why, but I think that any board needs to have some sort of community feeling to succeed. That feeling comes from a sound core of experts at the bottom, sharing their knowledge in a non-condecending way.
Perhaps welding is such a niche that the general public can't relate to it, contrary to a web programming community where everybody can participate without any investment.
Take me as an example. I love to design and construct things. I consider myself a woodworking master. I think I have wood-craft tools close to $ 50.000 in my garage. Welding is just a small part of it.
However, when I started to weld on a hobby basis, I quickly learned that I needed a TIG for precision welding. The price of those machines are breathtaking
Welding might therefore always be for the privileged few (apart from the professionals).
Additionally, welding is difficult and complicated.
Anybody can get two pieces of metal to stick together with a MIG torch, but it will be ugly and faulty.
Welding is complicated and requires an education, or at least a professional supervisor who can point out what it is you are doing wrong.
If you combine that with the high entry level price (machines), you have a topic that is gonna have far few members than the average webdesign forums that costs no more than the average teen-ager can afford (albeit the programming world can be far more complex than welding could ever be).
Point beeing, ..
The welding community is small.
The tone of the community in combination with it's level of expertise, is critical to success.
Jody's high profile (youtube) is the biggest reason for this forums success. That is at least the reason I came here looking for help. I guess many of the other welding forums out there are made by, and run by professional welders. I would never dare to post my trivial amateur questions in such a forum. I know (from Jody's videos), that this forum allows for people like me to ask questions without being ridiculed, and that some of the guys giving answers are hard core seasoned professionals.
So... People like me can post questions, amateurish and stupid, without being ridiculed and belittled.
