St. Simon

Tell me about it Simon ... I think some people have such a high opinion of themselves that they simply can't believe they are wrong, and normally they know little to nothing of the subject matter.

People were talking uninformed nonsense long before Youtube, the only difference now is that with the internet we come across far more of them! Adding comments, especially as a professional, is tricky because some people take it very personally as you are aware. One option is to contact them directly to avoid the public dimension. To be fair, I assumed signalling wasn't that complicated until I read your book and you kindly gave some advice to me on here!

Was it Bryans Planes perchance? ;P
