I understand though, I sometimes use that word if something really ticks me off. On vacation and it rains? Yep, it sucks! Someone wrecked your car, well you know how to describe it. Sooner or later, something just sucks.
But computer operating systems should be described differently. It something breaks, I prefer the solution or advice. If something really did suck, explain how and why so maybe someone might learn something. If humans really stop learning....man that really sucks!
