So I have a dislike of jargon that makes communication inaccessible to people who are inexperienced in the relevant area. It makes a barrier that new people have to work hard to overcome in order to be able to become properly involved in an activity, and definitely risks alienating and discouraging people who might then give up on something they'd ultimately enjoy a lot.
(It's important to note here that as a musician and a scientist, I know that technical terms are necessary and important and we shoouldn't discourage their use, but if you're wanting to explain something to a non-scientist or non-musician you have to think about the words you choose. I wouldn't use "ATP" or "adenosine triphosphate" with someone who hasn't studied biology (I'd say something about "cell energy" maybe) because they wouldn't understand and would perhaps switch off.)
And the point I'm making is, we all use abbreviations on here far more than I think we should. Sure, a lot of forumites are extremely knowledgable about the game and the card names/effects, but there are definitely some people out there who think, "WTM? WTF?" and it concerns me that this kind of thing makes us incomprehensible to the new people that we should be encouraging - more SotM obsessives is better, right?
Disclosure: I have a medical condition (fibromyalgia) which causes me cognitive difficulties - imagine being really tired a lot of the time and finding it difficult to think, kind of like you'd feel if you had proper 'flu and someone asked you to solve even relatively easy algebra questions when you're finding it hard to even keep your eyes open. And personally, even with my greater-than-average familiarity with and knowledge of the cards, I often have trouble knowing what people are talking about just because they've made up some cute nickname or are using initial letters or something. An fairly obvious name, like Akash or Gloomy or Grandpa Legacy or similar would definitely be preferable.
Now I'm not telling people what to do or trying to impose my will on the forum or anything, just asking that people think about it a little, and consider typing a few more letters to confuse new people a bit less (and make my life a bit easier as well).
