Having divided posters/readers here on RP into 'normal persons' and 'diicks' we can proceed from there.
At the outset the diversity of your posts far exceeds those of most of us and often covers a large range of rail topics, electricity generation, car engines, climate change, the economy, coal mining and aluminium production. To my limited knowledge these posts are uniformly reliable.
I used to read many of your posts with interest but I have tired of the inevitable unexplained acronyms. We do not all live in your world and I certainly do not speak your language. I suppose this makes me a 'diick'. If so, then so be it. I will stand by my record in the Australian Rail Industry which I do not intend to justify to anyone on here.
We all need, from time to time, to consider the content, accuracy, format and level of information we are posting on RP but having divided posters into 'normal people'and 'diicks' we can further divide those groups into those who post to inform or question and those who post largely to display their supposed knowledge. Clearly you do not fall into the latter category.
Undoubtedly, we are from differing eras, backgrounds, training and education (perhaps in the UoHK*) and all that I was asking was that you explain the esoteric and less well known acronyms that you use so as to make your posts easily readable without the need of Wikipedia (often useless), a dictionary (always useless) or having to ask (and be/appear a 'diick') and lose the thread continuity. On a rail forum what does one immediately think ICE?
My aim is not to pick an argument but rather hope to make your posts more readable to myself and, perhaps, more informative to any other 'diicks' here on RP.

End of rant. Keep smiling.
My position is this.
In a media that is typed, short hand creeps in, either through habit or for sake of time. If I'm in a Sydney based rail forum, then its reasonable to believe that most people in that forum would be familiar with Sydney and hence understand the term "NSL" = "North Shore Line". If I was to post in Brisbane based forum referencing Sydney's "North Shore Line", this I should use the full name or at least reference the acronym. However in the same thread should you do this every post??? Technically yes, but unlikely.
In the same token, should "Nth" be used over "North", technically no. But should someone also have to explain "ATM" or "TV" or "ABC", the list is endless?
What about the use of "XPT" or "XPL", the former especially is NSW based, but I suspect few rail fans or industry employees in Australia would need for explanation, but when was the last time you saw it written in full?
Our everyday language is full of everyday acronym's and as you know industry more so, if we were in the same room I could show my work email INBOX. (99% of more of my companies 6500 work force do not have English as their first language. for some reason they grab acronyms more so).
"ICE" in a rail context titled thread I would take as "Inter City Express", but in a thread on Electric Vehicles or "EV", I would take as "Internal Combustion Engine" and to be honest this is an acronym that I learnt in here, but now seeing increased use in other media as is the term "EV", "HEV", "BEV", "PHEV" etc, many of which I've also had to Google along the way. On a side note, "Google" is actually a noun, not a verb but now means to so something specific, but do we need to expand this or just assume common 21st century language?
My point and reference to my use of "the diick" comment. I think its the context and forum that the acronym or jargon is used and your expected audience on whether or not its ok to use up front or expand on use. Is it perfect English to never expand, probably not. I normally find if in doubt my own Google or simply asking for explanation without sarcasm also works wonders. Perhaps its the written media forum we are using that looses some of the personal touch and I took it the wrong way??? I don't have an issue asking for an explanation for an acronym, maybe I just so used to doing it. You obviously don't feel the same way, ok I'll see how I can improve.
Regarding your comments on my experience, I know about how to make aluminium, that you can be sure of and a few other material processes. As for the rest is 25% RP, 50% Google/Wiki, 25% other including personal experience and just an opinion, (sometimes too strong opinion, or others have too strong an opinion which is why I stay away from some forums in the Lounge) for which if you don't agree, feel free to challenge including the use of any acronym and enjoy the friendly discussion.
