Sorry for the long reply, but I thought I would have a go at explaining my philosophy on this forum.
Yes, this is an open forum, so you don't have to agree!
I am a DIY'er and don't proclaim to be otherwise; I have some all round experience from renovating my house and I need a good general knowledge for my occupation.
My interests and a good portion of my work, involves electronics and IT.
I occasionally post on the plumbing forum and sometimes, rarely, my electronics insight allows me to give advice, that might be missed by a gas engineer.
A poster on this forum may get advice from literally anybody. This is great, but also has drawbacks.
We all make mistakes and on a written forum, there is a lot that can be misinterpreted. Also assumptions have to be made when trying to understand a post.
However, if an RGI was to answer a post and potentially put someone at risk of harm, they put themselves, their career and the reputation of their profession at stake.
This is a lot of responsibility that isn't shouldered by a DIY'er.
For my own peace of mind, I don't dive straight in to answer a post. If I am unsure about something I am writing, I make it clear that I am a DIY'er and may be incorrect.
And above all I have respect for the people on this forum, that have a vast amount of collective knowledge and professionalism.
What I see from some recent posts is questions being answered with absolute certainty, when often there should be doubt.
This isn't just a 'forum', in some circumstances, the posters have a very real risk of coming to harm, if following incorrect advice - I take this seriously (and sometimes agonise over my replies).
A poster should be able to get advice they can trust - let's not make it any more difficult for them
