How many big boards have you built so far? Would be happy to learn how to build one.
I don’t build big boards, although I might have done around 2005 when they were all the rage. Have you noticed there's a distinct lack of people here with successful forums? I have a small blog I’ve just started which I haven’t even got round to start promoting yet. You don’t need to have a successful forum to know what an unsuccessful one looks like. I’m not a mechanic either, but I know if I put water in the gas tank it won’t work. It’s called common sense.
In the unlikely possibility I’d start a forum, I’d be looking at the few successful ones and trying to work out the reason for their success, not doing the opposite and hoping for the best. Lawyers, doctors, mechanics, people who’ve travelled … they all have everyday knowledge of interest that we like to read. If on the other hand someone has no knowledge of anything, no one is going to read the little they have to say.
Look at your online resume and everyone should have one. This is what you know about, this is your expertise, your combined knowledge and experience. In amongst the content should be what you’re trying to sell to an employer. You’re asking someone to pay you for your knowledge or experience. Now start a forum about it. Begin by writing a quick 500 words on your specialty or skill(s) and if you can’t do that or don’t have any, you’re probably not going to get the job, but you’re also not going to have a successful forum about anything either. That’s how to start building a forum, it really is that simple.
Personally, I’d find it as difficult to run a forum as others would making a blog, but whatever it is, a forum, blog, academic writing … If you can’t write content the Internet isn’t a place to waste your time, money and effort on. Ask yourself a simple question: What have you got on your forum that the people you're targetting would find interesting?
