Oh, I think if you have a real try you might get some glimmering of what I was on about.I dont understand. Genuinely mystified here at that.
We all talk tosh about stuff we aren't really experts in (it's the internet after all) and you're not really (or especially) immune - neither are the pro- or anti-K factions in your principal area of interest, who transform themselves into stadium architects, transport specialists, City financiers and media gurus at the drop of a Fellaini wig.
And sometimes people are a little bit more expert in their own areas than others on here, which can be informative or refreshing. And sometimes people might be wittering on about stuff they patently have very little idea about if they come into your or my or anyone else's area of expertise.
On the internet, as they say, no-one knows that you are a dog. But sometimes you can just about hear the barking and whining.
