Quote: So, what you’re saying is: it’s unhelpful to be over-enthusiastic, as such comments could be mistaken for fact, and misused in an erroneous purchase.
When you present them as fact, yes. Be as over-enthusiastic as you like when you make clear it's opinion.
Quote: This will be particularly unfortunate, as I probably have lower standards than you,
I have no idea what your standards are, nor those of the OP - and that's the point - you have no idea of the OP's standards, either. All we know is that a compact doesn't meet his requirements in this area.
Quote: and of course, you are looking after the interests of members.
Indeed so.
Quote: Why don’t you just say how you found the E5*0?
The results from it that I've seen are perfectly respectable, and IMVHO it should be on the OP's shortlist unless he is particularly demanding about high ISO performance. The E-520 appears to be a decent and sound camera that represnts good value in the two-lens kit. It's got a lot going for it. I'm absolutely not telling the OP not to buy it - it may be the camera that suits him best, and if it is, great. If he decides that nothing less than a Nikon D3 will suit him, that's great too - as long as he makes the decision that's right for him, it could be a film disposable for all I care. I find it utterly incomprehensible that anyone might take a different view to that, TBH - why should it matter to anyone else what brand somebody chooses?
