Empty comments can be ok if they're positive. [...] What we especially discourage are comments that are empty and negative—comments that are mere name-calling.
Any positive comment is fine, unless you are retorting to a negative one in which case you need to explain more.
If making a negative comment you should explain, i.e. "I think this is bad because ..." rather than "This is bad.". If you have a valid point you are helping by raising it.
Similarly when retorting to a negative point with a positive view, "I disagree because ... " is good but just "You are wrong." simply unhelpful noise.
So feel free to provide positive encouragement when you think something is awesome!
