I have read thousands of threads and what I have noticed is that in the older ones, most constructive posts don't get a single like. Whereas now if you say anything, you are being liked on that forum post. That is a good thing, it shows you that your posts are being read and respected by another fellow user on the site, as well as that it...boosts your like counter and fuels your arrogance...heheh...(although that is not the main point)
But the main thing is that in crucial threads here, most posts get not only a like but two or three, with the exceptionally useful tips getting five or more, whereas they are on par with the quality of posts of generally what you would expect a single like two or three years ago. Liking posts not only has been brought up, but it is a common behavior here. I find myself liking other posts much more often than before, before a certain point I didn't even realize there is a like button, and just read on without showing a feedback of respect even if I do. Discussions are really getting more civil, it seems, as you are firm to be respected no matter which standpoint you are on(although, a Nazi deserves no like on his posts exhibiting this view, obviously). Bottom line, I am pleased with it. Thank you.
