I haven't read the whole of this thread - I've been on the other side of my work/forum balance
I first came across the forum through a google search when I was looking for info on a company which I wanted to find out about. It happened that there was a link to forum and that's how I stumbled across it.
There seems to be a group who have no idea at all about business and come with very limited information but expect to be given a detailed roadmap to business success. It doesn't work that way, and although their naivety may have a certain charm, that soon wears off. Apart from the occassional reply along the lines of "Talk to a professional", I just ignore those.
By far the largest group post specific requests for information and those are exactly what I believe the forum is for. In my area of expertise for example, someone might want to know about tax-deductibility of expenses, or business structures. That's fine, and if someone hasn't already replied, I'll contribute where I can.
Only once did I stumble across a thread which really made my blood boil, and that was the 'ceiling stars' thread. Not though because of the original query raised, but because it went slightly off topic into an examination of the poster's quite distasteful business ethical standards, and that for me has resulted in one forumite to whom I will not give advice.
I've both received and given advice, and that's how the forum should work.
Blatant posts seeking business opportunities should be deleted, but other than that, I think it works reasonably well.
