I don’t have any problem with people expressing a point of view, but there needs to be points/evidence to prove that opinion and in particular within the context of a thread’s topic. In other words, you need to say why something sucks and how that relates to what’s being discussed.
For example, in this thread, one could argue that “Skype sucks” because the newer Skype versions have poor performance, and thus adding a new feature would likely make that problem worse.
Citing statements of opinion over and over without evidence might get you elected as President of the United States, but I think we should have higher standards
