Too many times, we read endless posts that are not concise enough. People are busy these days, and they are smart enough to get the concept the first time you tell them.
If you want to emphasise the message, you can say it twice. You can add an example or two, maybe a link, but then that’s enough; there’s no use in writing long posts that says little.
If you have little to say, write little. If you have nothing, write nothing. In the information-overload era, it’s unnecessary to add stuff over stuff, especially when this stuff says nothing. Of course, you could say the same about this post, but at least it’s short.
