I find it good to have a minimum amount of character and/or sentences!
After all, if your answer is too short, that means you add nothing to the thread. So that you shouldn't post at all.
Your post is false and longer than the usual cut-off limit, albeit adds nothing valuable to the thread. Let's follow your logic with an example:After all, if your answer is too short, that means you add nothing to the thread. So that you shouldn't post at all.

Is Bitcoin really a decentralized currency? How many coins can there be?
Quote from: Expert
Yes it is; a maximum of ~21 million coins.
According to you, this post adds nothing to the thread. 
The length of a post has nothing to do with its quality. A post containing a few words can be much more valuable and accurate than one containing a hundred words. Stop supporting this illogical and harmful idea.
Well my answer added my support to this idea and launched a debate between you and me from which might emerge additionnal content and reflexion. So it was not that useless ^^
Your example is a good one indeed! You see here the Expert answered quickly to the newbie. And I'm willing to bet that this answer is not enough! But with the minimal of 75 characters maybe he would have taken the time to answer:

Yes it is. The principle is that only the person having control of the wallet can decide to send coins and to which adress. And the payment process is noted and confirmed by the miners, who can be anyone in the world running the Bitcoin scrypt. So the only way to centralize btc (so to control it) would be to control the majority of miners.
The number of coins is limited by the definition of bitcoin itself, it's aroung 21 million coins.

I believe this answer is more detailed and would probably help more (maybe my explanations are not the best, I'm not an expert ^^).
The main idea is if you create the necessity of the 75 characters, it will reduce spam (cause spamming sig campaign would become more expensive in time) and people would get used to answering in a more detailed way. Which can't be a bad thing in my opinion.
