Thanks for pointing me to this article. I guess to be effective in this platform then generalised comments are ignored 9/10 times.

This platform (STEEMIT) is not a Facebook, in the sense there is no need to write general comments, even on FB they get ignored. So i agree after thinking about it, that by writing a general comment it's kind of a waste of time and doesn't contribute much.

I think people should know how to behave, so hopefully not many people need to take the "what not to do advice", I'd hope to think so :D
