They might be journalists in the visual media, but in the UK they are probably Grauniad journalists.
Looking through the threads I think any objective reviewer would quickly conclude that were only pilots permitted to post then the expertise to answer/discuss would be sorely limited.
Whether it be a thread on passengers standing up on scheduled flights without the input of flight attendants; discussions on the design of CVF without engineers; or discussions on flight separation rules without ATCOs, many threads would be very much the poorer if only pilots were allowed to comment.
However I am not a pilot so my opinion is irrelevant (Twos in got it right though)
