Seems like some people are unable to handle actual questions on anything that appears challenging and want to dismiss as being hyper critical and snarky for not just drinking the kool-aid.

There was no snarky tone-of-voice in your reply when I read it. Maybe cultural differences? Please, kindly inform me of the output of the power output per m2? Also, is there any information available regarding the durability (lifespan) of the product? Who's got time to be that formal on something as an internet forum? I read topic, now here's some questions I have is perfectly fine. Some people possibly just need to get thicker skins and realize that not everyone out there is trying to be an asshole and just stop reading things in that manner.

Honestly, I do not know how much technical my question can be, there is no tone, there is 14 words in total. I was googling and I could not find anything useful so I hoped I could get some answer from some technical person (material science/physic person). In my mind finding those number is the first thing I would do on the test bench, they give you prospect of technology some kind a range you would attract investors. You would have test sample 1X1cm you shine that amount of light and you get output. And then you know this is feasible and can help in future or not... simple as that. Instead I am getting some kind responses like I am talking with emotional teenagers tripping on some cry baby drugs... for heaven sake ... (yes that last is emotional response, I mean seriously what is going on with HN lately it used to be place with tech guys talking tech ...)

I suppose the tone could come exactly from the brevity. Imagine stepping up to a bakery and hearing “what?” instead of “how can I help you today dear gentleperson?”.

Which one would you find more snarky?

Even if the bakery employee yelled "What?" at me, I would not hear snark in that. I would probably hear rude, but not snark. I would also be a little less surprised if it was a very busy place and the employee was visibly harried by the commotion. Or if I was just in any store in NYC.

There's a difference between terse and to the point vs being rude. It's not the terse response's fault the recipient cannot tell the difference.

Also, are we using snark as a synonym for rude nowadays? I'm going to need to update my definitions as I was always understanding snark to be sarcasm. I just want to be using the same words as everyone else on the internet so I don't offend. (that was snark).

Edit: actually, if I went to a store and someone asked "how can I help you today dear gentleperson?", I would immediately assume they themselves were being snarky. That's like saying "bless your heart". It's just dripping with snark.

I always assigned “rude sarcasm” to snark but apparently it is just sarcasm.

FWIW, I didn't detect any snark in your words either. Perhaps brevity was mistaken for snark?
