I actually want the opposite of that. If I click on "disagree" I want everyone to know it was me. We're all busy folks, and at times there are plenty of incorrect posts. If a few reputable members click "disagree" I think that it should be clear that the post in question should be taken with a grain of salt. OTOH if a bunch of members of questionable standing click "disagree" with a post the reader has the opportunity to see that and still evaluate the contents of the post on their own merits. Same thing with liking or agreeing with a post. Sometimes a new member may try to give some advice and need a little reinforcement to show that the advice is correct... if a bunch of established members click "like", "useful", or whatever... that's a vote of confidence and lets everyone else know that they should be able to rely on the content of the post. The easier it is to see who's rated a post and in what way, the better IMO.
Disagree is OK but I think dislike is another level, so.......... BTW just discovered that you don't receive notification if someone liked your post anymore
I feel like there should be blue outlines as the icons, and a option to minimize the icons into one button to open a small menu. Otherwise it has like these tiny little buttons on a small screen. I had an iPhone 5 and the old like button was 3/4 of a centimeter wide. The new like system has buttons 1/4 of a centimeter wide! You have to zoom in to see the buttons! Now I got a 5.5 inch screen on my OnePlus 2 and I can actually click the like icons. So yeah, make the buttons bigger or add a pop-up menu.
Nice is pretty much the same like, but for more specific situations. Disagree on the other hand... I hope disagree will come back
